I just recently completely rebuilt my 2.5 for my 89 es. Now that i have it in the car i have some major issues. It will overshoot its idle and die, lacks power, and eats fuel. I put my otc 4000 on it and looked at the values on my sensors and was a little dumbfounded to find that on the screen with the electronic advance it stayed at 000 no matter what the engine rpm or throttle. I had the scanner on my 87 Z and at idle the advance was 012 and it would move around with the engine rpm. But on this one it just stays no matter the dist position. When i unplug the cts to set the base timing it just dies it will not stay running at all. I changed out the hep with a brand new one, changed the throttle body with a known good one, changed computers, and the kicker I have no codes at all. And yes i did all the usual checks including the cam timing which was set perfect while it was on the stand. I do have a question however about the cam. The cam is an 88 tbi slider cam with the 668? n/a cam gear. Will this have a detrimental effect on the cam timing. If so i will swap the 89 turbo cam and turbo cam gear back onto it. Any input would be greatly appreciated.
Thanks in advance.
