I think you might have the same problem i just fixed. Take your car by an auto zone or advance auto parts and see if there are any codes in the computer. I had a clogged cat causing the left O2 sensor to clogg full of carbon. Fixed cat and replaced O2 sensor and now have almost 2 times more power and no more running rough after its been run 10-15 mins. Hope this helps

 

has anyone investigated vapor lock? just a thought.

 

Have a major tune up done with wires. Sounds like you have oil on your wires. I see it all the time. Have the mechanic inspect the front of the motor from underneath and I am more than positive he is going to find oil leaks and saturated plug wires.

Let us know. If you are in Michigan you can come see us.

 

I had the same problem with my 94 Z28. My car would read hot and it would not give me any HP. I found out that the temp. gauge went bad. I've heard that some Camaros don't have them, so you would need to buy it. It solved my problem.

 

It's probably the fuel pump. Just because it has ok fuel pressure, it can still be bad. also check the regulator,

 

I am sure you have heard everything but I had that problem too. I would pull up to stop lights and it would die when my car was warm and lose power kinda like the battery was low and all kinds of other things. I later found out that when my engine was gettin hot it messed up my starter and solinod (however you spell it) and had it replaced and was good to go from then on out. Like you I took it to many shops and spent way way to much money, and finally found a hillbilly shop that found the problem. So you can try that and see whats up. If it does or doesn't fix it let me know. Thanks and I hope you get it fixed. Chris

 

check, the fuel pump im 100 % sure thats what it is, me and 4 of my friends all have 94 Z's and we've all had the same problem at some point, if you let it get worse, you'll have to turn it over 2-3 times before starting, and it may run worse..and eventually it wont run with the bad pump and/or regulator.

 

Hi,
I had the same problem as well.........it was the distributor,
it would run fine until it got hot then it would almost shut down.
