Ok I have one for you guys. Car started to idle high while I was driveing tonight, turned the car off, they it would not start. Pulled the ECU fuse for about 5 min then the car started. Turned it off again later would not start again just turn over and not fire. Well the battery I think was the problem replaced it still would not start for a while. They it started and was idleing about 1300rpm. Ran fine just idle high. Any ideas?? power kept cutting off and on for the whole car.
