Engine Hesitation

[88-5.0mustang]

Hey, I just recently bought a 1988-5.0mustang gt with t-tops and i'm having a rather annoying problem, basically, the car idles fine and runs fine under hard throttle, but when it is given just the tiniest amount of gas it hesitates and then kicks in, and sometimes even stalls.Its really annoying.... and embarrasing aswell when everones looking at u and u stall . If any buddy has any idea what could be causing the problem that would be great,
thanks

Well, you left the door wide open on this one. Check your plugs, wires, distributor cap and rotor. Check your timing, put it around 14*, and your TPS sensor, around 0.97. If this fails, try maybe some fuel injector cleaner or sea foam.

Check the TPS setting & the base timing. (follow the links for "how to's")

When was the last time the car had a complete tune up?

What kind of tranny? Automatic? Manual? Hamsters? Please be a little more specific.

Sorry, it a T5 tranny, the plugs and wires are all good, and the distributor contacts are free of corrision, right now the timming is set at 12 degrees, i am gonna go try and check the tps and see what its at and let u know back, thanks

Hey guys, Just wanted to let u know it ended up being the TPS, i checked it and it was at .85v so i justed it to .97v and it runs beautifully now, thanks again for the help

That's what I like to hear. Go hammer some Civics.

Tweaking the TPS to cure hesitation problems? Makes me want to tear off all the efi stuff and go with a carb.
