Does anyone make an improved version of the throttle linkage between the firewall and the intake manifold? Here's the part that I'm talking about: I'm chasing sticky, non positive throttle action and have found that my throttle linkage is sloppy and worn at the plastic pivot up by the firewall: I know I could clean and lube it to fix the sticky part, but that won't do anything to fix the sloppy part. Are there aftermarket options out there or am I looking at a custom repair?

Hello fellow Z owners! After driving my Z the past few weeks, I had noticed the vehicle had a "Hard Start or Stutter" after it had warmed up and was restarted. I put 91 fuel and injection cleaner in the tank for a week. No change... I had also noticed an excessive fuel smell while driving my Z and especially after filing her gas tank. Enough was enough I had a massive headache each time I had taken the Z out for a drive. I decided to check my Air Flow Meter (AFM) was operating just fine, Also checked my Cold Start Valve/Injector that was fine. Lastly I decided to tear the Fuel Injectors out (Stock) and looked at all the tips and hoses. Hoses were fine...The tips were crac…

HI All, I haven't been here in a long time but I have been gradually working on my 76 280z. Lots of new parts including all new injectors (this car came to me in pieces and with some missing pieces, including the entire exhaust system). Anyway, it runs but runs rough when cold, not bad when warm but still seems like it should be smoother. I was running through some of the resistance checks in the EFI manual. I had suspected the air/water temp sensors because it is running pretty well when warmed up but those checked out OK, at least the cold measurments did. Anyway, I was surprised to find problems when checking the AFM as it looks like the guts are new. Here is wh…

'77 to '78 hose changes from valve cover to AAR. It keeps the AAR cleaner.

Hey All, My father and I have brought back to its former glory a 62k, prior one owner, 280Z 5 speed. We did some concours/close to concours bodywork/paintwork and are working on the finishing touches. One of those finishing touches is getting it running real nice. Here is some background: -Sat for 20 years or so (prior owner passed away) -Prior owner's brother this year drained the old fuel, put on new fuel filter, new fuel pump (not sure what brand), and put on a fuel pressure gauge -Tank has at least 4+ gallons of good fuel in it right now. So here is what happens: When we first start the car, it runs real sweet! Nice and smooth, revs up all the way real easy, etc.…

Messing around with things and I cut an FPR open, mainly for the mounting bracket, but also to see what the valve looks like. It's a steel tube mated against a steel disc, both highly polished and very flat. You can see how a little bit of crud or even just a hair could cause it to leak.

Got the engine started right away after following advice given here...started right up, but rough...replaced fuel pump, cleaned injectors...runs a little better but no throttle response ...feels like it is not getting enough air(?) I do not have enough tech know how to do the multimeter testing at the ecu so thought I would start next step by cleaning the MAF...is this a good way to go? and should I use any special chemicals? I have the Deoxit...mentioned in some of the posts I've read here.
