Re: Busted Alternator... Suggestions?
Where to start.........
That you have described is a 'logical fallacy'.
It is etremely unlikely the alternator is related to your idle problem.
Many cars will stop running when you remove the battery terminal. Not all alternators will keep the car running without a battery hooked up (even a bad one). It is a function of the wiring that some cars have.
If your alternator produces 13.7 to 14.5 volts with the engine running and the lights on, its fine.
More than likely you have a problem with the throttle body, and especially the idle air bypass valve. This valve controls the idle speed of the engine. These require maintenance, such as cleaning. They mostly get dirty due to the PCV valve.
I would suggest taking it to a mechanic who can scan for codes and clean the throttle body.
