Car won't idle... engine dies

NissanSentra99 · Apr 28th, 2008, 08:32 AM

I left the lights on, my battery died, I jumped started (boosted) the car with a second car, I think I blew the alternator.

Had the alternator rebuilt – Now I’m getting a 12.5 volt reading when engine is off and 14.5 when engine is on.

But car won’t stay in idle by itself… When I turn the key, crank the engine, I have to keep the foot on the gas or else the engine stops

The engine turns properly and everything seems to be working other than this.

HELP

Did you by any chance had the jumper cables reversed when ready to hook them up? If so, then some component(s) may have been damaged.

Nope cables although not new were correctly positionned...

I've been told to check IAC valve, TB, etc.

Hope it's not the ECM
