Q: I have a 96 Isuzu trooper that while driving with the AC on, the voltage meter will jump all the way up, after about five minutes.
I have a 96 Isuzu trooper that while driving with the AC on. After about five minutes, the voltage meter will jump all the way up, the engine is bogged down when trying to take off and when i put it in park the engine races up. When this started, I had the battery checked, it was bad so i replaced it. Today i replaced the AC belt. Still doing the same thing. If i drive without the ac then it runs fine.. Ive read it could be coils, O2 sensor, or alternator..please help
