1998 GT

i just recently cracked the intake on my car and replaced it with a pi one and my fuel pump went bad so at the same time replaced that. It should have taken care of my problem but my car still sputters from take off. could it be a bad injector? ideas?

check your tps setting

did any coolant get into the spark plug holes/ports when you replaced the intake? Pull the boots and look. If you do have coolant in them, you may have bad plugs. On my car (98gt) there was coolant in the plug holes on the drivers side. I blew out the coolant from the holes and the car ran better. I just replaced all the plugs yesterday, now HOLY CRUDE totally different car. I think a few of the plugs that got wet were not firing consitantly.

idk about the coolant thing ill have to check that out and remind me what is the tps setting? thanks for all the help guys

tps= throttle position sensor tells the computer how deep your into the pedal and which fuel table to be on according to rpm. i dont have the procedure off hand for a 98gt so you will have to look around

my 98gt does the same thing ever since replaced the top end with new ported npi heads with cams and pi intake. its weird mine only does it when i take off with alittle gusto. if you didn't drive the car normally you wouldn't even be able to tell its happening. haven't really been trying to find the problem because it doesn't seem to affect the performance of the car at all over all. so hope somebody knows whats going on with our cars lol

well mine really seems to hurt the cars performance. it doesnt do this all the time but its really frustrating when it does. im getting ready to change the spark plugs to see if it helps any.
