I just replaced my alternator.........with a new alternator and it works fine but my car seems to have lost throttle responce and power anyone ever had this problem after replacing an alternator?

Did you get a larger one?

No just the same stock replacement one. I may have fixed it all ready, I disconnected the battery for a while (30min) and it seems alot better all ready.

You reset the ecu.

Run a larger ground off the Alt.

Yes I reset the ecu also............Thanks alot for your guys' help.

While driving what voltage are you guys seeing?

What is it suppost to be around?

I typically see about 14.0 volts when driving. At idle I'll see a drop to about 13.5 volts. Some accessories like a rear window defogger will zap about 0.5 volts.

I have 14.5 at idle up front. And 14.3 in the back where the battery is.

My MDM-100 says 14.1v while driving and idleing, and 13.5v when my belt slips and makes all kinds of crazy noises!:D
