idle problem please help me out

[dsmgearheadtune]

i have a problem when my 95 gs gets a temp of 145 or higher, it seems as if it lags when i slightly puch down on the gas, but then when i press on the gas all the way it doesnt lag, ive done many things to take this prob away, fuel filter, nes vaccum lines, i use the injector cleaner ever time i fill up, would it make a difference if i used cheaper gas? i also did plugs wires.

Have you tried taking up any slack in the throttle cable? That wouldn't explain why it did it only when its hot but I'd give it a try.

ive never tried to take up the slack but i dont think i have any but ill check it out and see, but it doesnt only do it when its hot its startin to now do it evne when its cooler, but only for a short period of time, then it stops and acts fine, i talked a an automotive mechanic and he said it could be the injectors needing to be clean and id do it but im pretty pressed for money at the time.

i fixed the problem, it was by an accident, i found a vaccum line cracked that went from the intake manifold itself to the valve cover
