88 IROC 5.7 tpi, warm start issue

Starts right up when cold but I have to push the gas pedal to start it when it’s warm? Any help would be appreciated . Runs great after starting

If you have to floor the gas, that's "flood clear" mode which turns the injector pulses off so that excess fuel can be drawn into the engine and got rid of, and probably means that an injector and/or FPR is leaking fuel into the intake.

if they are the stock injectors the coils may be bad. Try checking the resistance on the injectors when they are cold and warm. They should be around 16 ohms. Let us know

Start by pulling the fpr vac line and check for fuel. If that’s good you have leaking injectors .
