FROM PERSONAL EXPERIENCE:
1996 CAMARO Z28 5.7L ENGINE TROUBLES
The symptoms continue in an intermittent fashion. Sometimes it was happy for months with only a nerve racking sputter or two while at idle or even cruising at 70 mph. Then suddenly it just stops running. Crank, crank, crank but, not a plug fired or was it that not an injector injected. In any case the thing lay dead for half an hour before it just came to life again. It was fine for weeks after that.
Overheats- Runs Rough- Runs Very Rough- Induction Backfires- Stalls Out-
Won't start- Check Engine Light Turns On-
Various Cylinder Misfires- Overheat Condition- Oxygen Sensor Failure (Totally legit but, not related to other issues.) and a few others I forgot about.
Overtime; I ended up replacing everything I thought could have been even remotely related to the problems, including the Engine Control Modual/computer. SOS!
Three things I came to notice about this whole miserable affair were:
OK... Cutting to the chase now--- The problem turned out to be a poor and erratic connection between the Engine Coolant Temperature sensor (The one mounted in the front of the water pump...) and its connecter. A serious cleaning and "tightening" of the contacts inside that connecter was “The Fix!!!!”
Me Z' has been up & running like a bat outta' hell for over 3 years since I cleaned up and tightened those connector puppies... I mean it hasn't missed a single beat!
I think the poor and electrically chattering on and off of the connection was doing an input signaling number on the poor computer such that it didn't know how to respond. Under those conditions, whatever it did decide to do in response like, turn off the cooling fans, turn off fuel injection, go full rich injection, adjust ignition timing, were “Just Wrong!”
That's my story and I'm stickin' to it! I hope this helps you and some others who have been experiencing this sort of thing.
