ok to start i am going nuts trying to find it. heres my problem if the car is cold it will start fine and idle fine that is until i step on the gas just a lil bit and the car brakes up and back fires. let it warm up and u can rev it up but if u put it i 1st and start to go the car brack up again and will do this for maybe 10 to 15 mins of driving and wen its hot it will run perfectly. ok now say i stop to get gas turn the car off go to start again just turns over over over if i hold the gas down all the way to the floor then try starting it starts right up. the car is an 87 gt speed density. has the flowing done cobra intake under drive pullies msd cap n rotor full exhaust system adjustable fuel reg.

what i think might be wrong with it. injectores leaking or bad, the flange on the top of the gas tank feel and messed up the fuel pump (have new one ready to go in) or the adjustable regulator is bad (also have a new to go in)

thanks
