Yea Greg! You woke up my favorite thread. I've been listening to a lot of music lately. Coffee in the a.m, music in the p.m. Never heard this before and it's seven years old. I am not cool.

Have you tried putting the car on jackstands, starting it up, and putting it in gear to see if you can locate the noise while it's up in the air?

The other thread seems to be gone but so is @siteunseen 's post that was in it. Oops. The test for the sporadically bad ECU problem is to bang on it. I don't think that it will show up from the Nissan test procedures. It might show up on a scope if you had one. That's the big thing at the small repair shops on the Youtube channels, they have scopes that they can take with them as they go for test drives. Pretty cool, but takes some money and know-how.

The richness and erratic running kind of fit what's been reported for a failing ECU. I had one fail as I was testing it, but it just died completely as I was road-testing, then restarted after a few seconds. It did this about three times before it wouldn't restart as I tried to get home. I was about a mile from home. The exhaust smelled like fuel as I tried to restart it at the end. I ran home and got the original and the engine started right back up and was fine after that. Anyway, short answer, people have had luck diagnosing it by banging on the side of the ECU or wiggling the wires to it as the problem is happening. If the problem clears up then you know it's in the ECU. Apparently the problem is caused by broken solder joints. People have had luck reflowing them, I didn't try on mine. p.s. since the "problem" is fairly common it can be defined as an "issue". That's just how words work.

I always say: He's less than a pile of s-h-i-t ... because that's useful to get some great potatoes or so!! Maybe he wants to come on the top of the list? You know... where hitler is on?

Thanks calling me but , I have no idea what this car is . Looks like a hand crafted Silvia inspired two seater . Kats

I voted to join Holland

Well I did get another lid and have both short ears on there . I have my float sync tool and messed with float levels forever . I come up short- no matter what I try to get the correct height . I said time to try it . It seems the engine want at least 4 turns out to be happy . That also varies from start to start . I need to check the incoming fuel pressure to make sure it’s adequate or maybe too much . I do have my wideband working so I am shooting for about 13.5 at idle . . Did I say I hate carbs :-0

It's false Fall in Georgia. That means for a while we will have cooler temperatures for a short while, followed up with a last blast of heat before true Fall. Anyway, the conditions were great for going to a Saturday morning car meet. As a matter of fact, the weather was so nice, several others decided to bring their Z cars out, too. The two yellow 240Zs were purchased through BaT. One of the owners has been to a Georgia Z Club meeting, though I don't know if he joined, yet. I ended up diagnosing "lack of cabin heat" issues on both. The brown 280ZX and black gold AE are both owned by fellow GZC members. All I can say is that the 260Z felt great on the roads with the new inner LCA bushings. I need to consider doing more suspension work on the 240Z to keep pace.

Consider using adhesive backed Velcro strips on the cloth seat back and belt. Fairly easy to remove when not needed and the Velcro should hold the belt tight. Dennis

This will do the trick,
