Gav240z

Thanks for the help and suggestions guys I worked her out. Turned out to be a fowled spark plug on cylinder 6. I pulled 1 plug at a time while she was running and noticed 6 made F' All difference . Pulled it out changed it with a spare plug I had in another engine and she was fine. Believe she's running a bit rich but nothing I didn't know already. thanks again and I'm so relieved hehe.

Oh yeah I get so paranoid DDing my Z I swear I've said it a million times people actually go for my car. I swear there out to get me . In a couple of years I'll be finished studying hopefully and be able to store the Z and daily drive something else and yes I too have considered a new 350z . Have you seen the engine bay? Looks like a science to change the spark plugs yike :tapemouth

@ BAMBI always hanging it on Zmefly . I find it funny he knows what a T5 is but doesn't know where the oil change plug is .

Welcome to my world and dilemna. I would really like a Daily Driver car to hack about but it doesn't take long before I miss driving the Z. The best feeling is when you have the car off the road a week or 2 cause your working on her and you replace worn out parts then hop back in and drive again. It's such a thrill just liek the first time you drive it again .

Thanks for the insight Alan and couldn't agree more with you . Really like the look of the Works stuff.

Little black box is a stardard item on the electronic dizzy. Forgot the correct name now, I pulled the 6th lead and found it makes much less difference than the others when i take it off but when i reconnect it, makes a little shudder as if it's firing a bit but not anything fantastic, electrical timing seems fine at about 11 degrees at 700rpm. Next problem is I need to pull the plug and the socket I need, my childish step father has locked up the tool box with it in their because I apparently don't put things back properly at 21 you'd think he'd treat me like a grown up not a child, I've been buying my own tools lately in an effort to get him off my back . By the way Nissan has those little black boxes priced at a pretty penny in the way of $800AUD. Hoping it's a dud plug will keep you guys posted.:devious:

Yeah didn't think it was the leads either, but still changed them the timing is set to 10 degree's or so but it should probably be around 5 with the 10:1 compression however i just checked it then and that was with the choke out so probably above 1000rpm. I would have thought capacitor too but it's electronic dizzy. I have a unique exhaust system and it's set so that the first 3 cylindes and last 3 cylinders split evenly into two pipes and come out the middle of the car like the works rally cars. I noticed when i put my hand over each exhaust the left hand one is blowing alot more air than the right hand one. I might give the carbs an adjustment but it really seems electrical cause when I rev it I can hear it miss. And even when one carbie is sucking more than the other you don't get that kinda missfire and the backfire however she only backfires a little when driving. What about on the side of the coil there is a wire that goes to the thermostat but before that goes to the side of the dizzy and there is a little black box could that be causing problems????

Well today I got into the Z and was on my way to check out a 2+2 for a friend who's in the market for one when my Z played up on me. I started her up let her run a couple of minutes while brushing my teeth :classic: . She's been running a bit odd lately and I thought it was a carbie issue could still be but it seemed like it had been missing a little but was driving fine. Last night I got her home no problems except well it seems like its outta tune. Now this morning I'm driving out of my drive way and start to accelerate and it's missing like mad so I think maybe the choke is screwed as sometimes they don't open evenly due to been worn or sticky so I pull over pop the hood and fiddle with the choke seems fine(I've never had a problem with the choke). I try no choke and same deal missing like mad give her a rev still not good. So I drive along waiting to see if when it gets warmer she's ok but nothing and it's been starting to backfire aswell. I check all electrical connections everything seems to be in order. Now recently I replaced my spark plugs so I count them out. my distributor is electonic and the coil is new and a bosch unit. As I say car as been fine for a year or more since I've owned her. I'm personally thinking spark leads as they appear to be a good brand(NGK) and I'm told they last forever there the see through ones. However everything gives up so I won't rule them out and probably before I have any reply to this I would have bought new ones anyway . So if anyone can suggest anything at all that might also be causing this please let me know. As I say I think it's mainly electrical not carbie but don't wanna rule anything out. Thanks

Yeah the speedo cable has an o-ring and if not there it will most likely leak. I gave mine a slight amount of gasket gew and I also had a leak at the reverse switch which I used gasket gew once more no problems I've seen and the garage floor is grease free. Oh and be careful once you remove the speedo gear it will leak oil have a ice cream container ready . BTW Sulio I need to speak to u your mobile was off at 11:00 today it's regarding cruise I'm having some trouble with my Z see my post I will be posting now:cry:

you will find alot of Z's rear ends clunk and it is generally considered normal. Glad to hear you are still having fun and great to see you've been working on her speaking of which I have work todo Try http://www.geocities.com/zgarage2001/z.html for tips about rear end clunk.

So true original does look great where did you get the picture Ben I don't see many ZG's in red at all. Also your avatar has a real nice looking Z have you got more photo's I'm just a sucker for the rear wing and flares . http://www.classiczcars.com/photopost/showphoto.php?photo=284&password=&sort=7&thecat=998 http://www.classiczcars.com/photopost/showphoto.php?photo=283&password=&sort=7&thecat=998 Same airdamn but as my other one above but I like this one alot.

Just make sure you have a adjustable wrench or monkey wrench as some call it. It's a Square bolt and it's the only one I could get to fit it.

which one the one i like or the one alfa posted?

I agree keep everything connected as it should be my last 260z had all of it removed in a feable attempt to suck more power out it by the last owner. Shouldn't have bought it but we live and learn to tell others not to make the same mistake. The engine was driven Very hard as I was longer and dumber then and just got my licence by the end the oil pressure was very low and I'm sure over revving , poor maintenance and all that so called performance robbing stuff was a part of it. Thank you Australia for your wonderful smog laws in the 70's

Forgot to mention Eleanor from Gone in Sixty seconds the Mustang GT500 and some of the replicas have been going for big bucks and there certainly not original by any streach of the imagination. Maybe to make modified Z's worth more we need to glorify these cars in a movie and then modded examples will be worth SH$! loads

Seriously what bambi is saying is the best idea. Is the 4 barrel carbie just a single downdraft? If so don't even bother sure the SU's can seem a pain but once you understand them there not all that bad. I agree don't pay anything for those flat tops. Especially if they look rooted I love this quote from ztherapy."This is not a carb-It is a boat anchor!" get's me everytime. Fuel injection is probably the least maintenance but setting it up initially is what will cost you and it makes your engine bay a bit messier I feel. But you can change that but replacing a few things. I've been wanting to order a set of rebuild Ztherapy carbs lately but I think my best bet is to buy the rebuild kit SM needles for the L28 and watch his 4 hr video on setting them up. Cheers.

Not sure I can say I like it at all. I love the Gnose as im sure alot of you know and I think this defeat the purpose of it. The gnose it meant to make the car sharp looking adding that makes ugly to me. I've attached the one i like

It appears I unsubscribed myself from this thread by accident when I was trying to change my email address so that this forum would send them to my new address instead of hotmail. All this talk has prompted me to call the PO of my Z and just make sure he still has the original engine block. He does and I just let him know his little baby is still doing fine :classic: . 240z in OZ I read through and understand what your getting at. I also noticed there was a bit of debating going on that was firing a few of us up . I have always loved Z's but I do love the ZG and 432R's so much so I've wanted to make mine into a replica but I've come to a stage where I figure it's not one don't make it one and maybe when I finish my degree(S) I'll be earning enough money to add one to my collection and keep my HS30 the way she is for the most part. Mine has an L28 that didn't bother me when i wanted my car because it was done well and the engine bay was mainly stock. Sure the head had been moded and everything but it was a little hot rod. I drive mine daily and yes it's a very nerve racking thing. I leave spaces between cars so that I have plenty of time to brake and often find people dodge in and out infront of me. I've been honked for going too slow by a civic when I was really just taking it easy the bitch was in some rush and her b/f yelled at me so at the lights I told him to take his $^!# heap and well you can guess the rest . I would love another car for daily driving I agree the HWY is awesome with a Z unless you have worn out Uni joints that cause vibration above 100 km/h . Seriously though traffic driving is nasty for the Z even reviews on the car 30 years back state that the clutch is hard in traffic and it's not a traffic kinda car. But that's just it isn't it? I mean the Z is a pure car it's meant to be driven and driven properly through the hills etc.. not stuck in traffic for 15 mins. I for one try to mod the car so that anything I do is easily reversible. Stock there fun to drive but modified there even more fun. I remember when i had to get roadworthy they made me change the muffler to make it quiet. I'm used to a 120db weapon. When I drove without it I really missed it, infact the car wasn't the same till she got back her throaty rough crazy sound . My point is that I would love to have the best of both worlds and I think i manage to meet that half way. At least I have the option to go back to orig or modded I guess and as long as you enjoy it, don't really let it bother you. I think its a shame Z's are disappearing off the road but at least it makes you something or a rarity and we may be a minority but I think we are all very knowledgeable and like to help each other out which is great. Can't think of the amount of times I've been to other forums and realised that most car enthusiasts have no idea what there on about simply because newer cars are not DIY friendly. cheers
