Hey all! just getting back into the Z world after being AWOL for almost a year. I had a technical question about a problem I'm now having while trying to get her back on the road.

I've already posted the question at zcar.com but hoping to get more input from you guys.

Here is the original post...

Cut n paste:
Hey guys it's been a while. I got under the Z for the first time in almost a year. She's been collecting dust and cob webbs...and I've been pretty much AWOL from the Z community also. Part of that is because the problems I've been having with her shortly after the engine re-build. Well, I sat in my car and I got that feeling again...kind of like my Z is telling me to fix me! lol...I guess that sounds corny but putting my hands on the steering wheel brought back a lot of memories. Now I've got the energy and drive to work on my baby again and my first step was to follow your advice and replace the fuel pump for the problem I was having with her. I got a great deal on a Vortex T-rex fuel pump and bolted it right in. Everything started up just fine after I checked the fluids but the stumbling problem is still there. Once warmed up, I can gas the car in neutral to build some boost but it would burp and gurgle as if the car is starving for fuel while it struggled to build some RPM's. While the car is moving under load I can get about 3psi before there's a major loss in power which would normally force me to let off. Also the air/fuel meter is reading to the faaar left (lean) at speed while boosting and while revving the motor at idle. So so far, I've replaced the fuel filter and replaced the fuel pump. What's the next thing that I should check? I've been told a lot of things like the fuel injectors are clogged to the O2 censor is bad or that the Air Flow Meter is the problem...I honestly do not know where to start next. I'm guessing the fuel injectors but hoping to get some educated advice from you guys. I'm so feening for that power again and just want to do what ever it takes to get her back on the road.


Thanks for any help!

 

Hey thanks for the reply. Got lucky though....she's running good now and all I did was clean out the ECU contacts. Worked like a charm. Thanks!
