92 Z NIGHTMARE

[rhipsher]

This is what I'd do if my Z started to act up like the above described. I'd force it to throw an SES which in turn will store a code. If its stumbling when you get on it than you need to really get on it. I can almost assure you that when you hit somewhere around 7k the SES light will appear in the information center and will turn off when you back off of the throttle. And there's your code. I was also going to suggest checking to see if your MAP sensor hose is plugged in. It sounds like a stupid thing to overlook but I think we've all done it at one time or another. That will cause terrible idle and run like crap. Once it's plugged back in it will purr like a kitten. But the code will tell you where to look.

I had an intermittemt miss that turned out to be a weak fuel pump. replaced both pumps and problem went away.

You need codes to appear

CODES would be great!!!! I'm the tech for ACI and most things that go wrong on corvettes I know from experience. I haven t had the pleasure of too many LT5 cars however. (Would like to get my hands on one to stuff in my 93z28. Hmmm fun times. )I'm starting to figure out stuff tho. I thought about the fuel pumps too, maybe Monday I will recheck fuel pressures.
