OK, I've had this horrible hesitation problem that happens intermittantly at all sorts of odd times and there is no rhyme or reason to it. I think I made progress though.... I ran all of wiring in the engine bay under the fenderwells recently and thats when this problem happened. Well I just looked under the pass fender and saw a relay dangling there banging against my wheel because I was apparantly too lazy to mount it correctly. I looked at it and the wires at the harness are all corroded and some are bare. Well I tucked it up where the wires were probably grounding to the chassy and took it for a spin. Man, my problem was 100 times worse all of a sudden! The car jerks and surges like crazy and revs up and down radically at idle. I found out the relay in question is the WOT relay. So I cut it off and reran the wires directly to the relay since the harness is junk. No change. My buddy did some checking and found out that in ex-aod cars you cant use a 5-speed computer because if there is 12v at pin 30 on the ecu harness then it will fry yer puter. Well my car is an ex-aod car and i threw a 5speed puter in it at the same time as when i reran the wires under my fenders. I havent had time to check for 12v at pin 30 yet. So, do you guys think my puter is fried, or maybe just the wot relay is bad, or something else in that circuit?? Please help.
