I bought a 1991 C4 with 19K. It is a 6 speed, with Trick Flow heads, aftermarket chip, BBK throttle Body. The car ran fine for the first 6 mos. Now, when I first start the car it runs fine. After the engine warms up, it won't idle and it surges, especially through third gear. The weird part is, none of this happened until a real hot day (~117 degrees). It was almost like something got damaged in the heat. I've replaced the plugs, wires, cap, rotor, and even cleaned the injectors. I'm at a loss, any help would be appreciated.

Thanks

Mine did the same thing a few years back. Turned out to be an injector shorting out. Do a resistance check on all your injectors (takes about 5 minutes) and I'll almost bet you find the culpret.
