i have a 97 coupe that threw about a half dozen "abs/traction" warnings last year. but i would shut the car off and restart it and it would be fine. but now this year it did the old "abs/traction & reduced engine power" when the car will barely run.
it did this once and then i cleaned the two ground plugs in the engine compartment behind the headlights. and i started it up and it did it again so i pulled the battery and tray to inspect the wiring harnesses under it and cleaned the ground there at the same time. and i drove it to work today(approx. 15miles) and it's been fine.
i pulled all the codes in the comp. and i was hoping someone could tell me if there is one specific ground i should focus on by looking at the codes stored in the comp.(only one was current P1033)
i appreciate any help you can give.
