i got an 88 gt convertable... it runs fine pretty much... when i punch the gas real fast, and left off right away, it has a slight hesitation, and i know its not normal, and i just put on a cold air intake, and i'd say it got 30% better, but its still noticable. i had this prob for a while, so i got all new wires, plugs, rotor, cap, fuel filter, even a tps and im not sure whats left, could it be a small vacc leak somewhere? any ideas? anything will help im sure

check your timing it should be 10*, try setting it to 11 or 12.....

BJ..I believe you hit there
I'm thinking is has alot of miles on it and the timing chain has a lil slack<edited><editID>vfast</editID><editDate>38001.4575925926</editDate></edited>

also you could be running a little rich. what mods do you have?? most likely is timing though.

the timing is at 12.....i got the cold air intake and the computer chip, and headers and straight pipe... and a few other small things, and its efi... it might be running ritch, but im not sure

what voltage you set the tps at? and have you checked the 02 sensors. do you have a stock fuel regulator or an adjustable?<edited><editID>bmorrisj</editID><editDate>38002.537662037</editDate></edited>
