Hi,
I just joined the forum as it seems to be an excellent source for info. My gf has a 1996 Pontiac Trans Sport with the 2.3 engine. It has been acting wierd lately, first the ABS light came on after some driving, the charging system seems to malfunction as the gauge sometimes shows charging, sometimes not. Today while driving on the road the idle went to 3000 rpm and when coasting to the side of the road (in neutral, manual trans) the engine died by itself. Then no start as the battery seemed to be dead, she got home by a jumpstart but there was no visible charge at all during the way home. The high idle thing has happened a couple times before but without the engine dying. Is there a throttle position sensor or mass airflow sensor that could cause this as a separate problem to the charging? Or is there any chance that all these things are connected somehow?
The alternator is new and the starter is rebuilt. The battery is seven years old and needs to be replaced anyway but the high idle and engine dying pinpoints to something else. Or is this just a case of having multiple problems at once.
Any help appreciated.
