What the *beep* is wrong with my car? Help needed!

smacksube · 07-31-2002, 09:25 PM

my modifications....
intake, exhaust, test pipe, hi-flow cat, clutch and flywheel, gab coilovers.

my problem...
every time I hit a bump, by bump imagine the tiniest lump in the road, my car cuts out and bucks. When the car is not in gear it will just stall. I can maintain an idle when sitting still, but any bump in the road will stall my car. I checked the spark plug wires and they were all corroded blue. Even the coil pack connections were corroded blue. I changed the spark plugs, wires and cleaned off the coil pack. The car acted better, but by the end of the day it was back to stalling, bucking, and hesitating. I ran my CE light last time this happened and got irregular map sensor (replace broken exhaust components) and low o2 voltage. I changed back to the stock headers and bought a new exhaust. Both of those were pretty damaged. The car was fine up until now, abuot 4 months. I don't know what is causing my car to buck and stall this time. I was told it was the o2 sensor, but last time the o2 sensor went out the car acted totally different. Like I could drive it down the street different. The car runs super rich, all the spark plugs were burnt black. If anyone knows what up, please inform me. I can't afford a new o2 sensor and was thinking about just unplugging both of them or just the one towards the rear and hopefully my car would run like it did last time, at least driveable. help.... THanks.

damn....there are quite a few grounds in the engine bay....hmmm....single point ground time maybe? I think so

The only other thing I can think of right now, is making sure those spark plug wires are nice and snug...or maybe the coil pack is bad. Take it to a dealership and have them test it...is your car still under warranty?

When I replaced the plug wires I got a wrench and kind of crimped them so that I have really gank on them to get them off the coil pak. Even if the coil pak is bad, how come the tips are corroded blue after 1 week of driving? Hmmm...why couldn't we get a cap and rotor....then timing advances would be easier....stupid coil pak....

I'll get a multi-meter and read what the wires are volting at.
