overheating, fuel cutout issues?

[Loren]

It is stated that the car is overheating. How do you know that? What is the actual temperature? Is the ECU storing any fault codes?

The only time I got any behavior of that sort from my car, it was due to a bad spark plug causing misfires at very high revs. (banging the rev limiter in 3rd coming out of turn 17 at Sebring) In my case, it would sometimes toss a misfire code, and a couple times it must have been so bad that the ECU just shut down and went into limp mode until I restarted the engine.

A new set of standard (non-unobtanium) NGK plugs fixed that problem.

So, be certain of what you're dealing with. If the car IS overheating, then fixing the fuel system surely isn't going to cure THAT problem.

You didn't mention what mods you have on the car. It seams reasonable to assume that you're turbo or supercharged with the way you're talking about fuel management... but I think some people here are assuming that you're stock.

What are your mods? What are your ACTUAL engine temperatures? What else do you know about this problem that you're having? Approach it logically and you'll find your solution.
