When I start my car like normal goes to the 3000RPM then drops to about 1500-1000RPM and will sometimes start to bounce between them two...And then once warmed will go to normal about 750-800RPM and sounds great but once I say put on the air or even the lights, anything taht uses power will make the car start to die and I have to hit the gas... But it will drop to like 200RPm and then I can save it so I think it shouldnt be a big prob.

But what would this be??? Everthing else in the car is perfect my engine only has 21,000 miles on it.
So maybe a tune up will help?

Thanks guys.....

One possibility is loose or dirty battery terminals,although it is sometimes difficult to start when this conditon exists.You could also check your alternator drive belt it should be fairly tight.

Sounds like you need to clean out and test your BAC (bypass air control valve)

I have the same problems, only mine doesnt stall every time. I've had my alternator tested and it is good, battery connections are good, pulled, cleaned and tested my BAC seemed to be fine. I'm not real sure what to look at next. If anyone has any info please post it. i will keep workin on it myself and ill let you know if i find anything.

BAC.

Alternator possibly... or BAC... or the voltage regulator, which is inside the alternator anyway.

check the ground from the back top of engine by the tranny to the spade clip on the firewall. i left mine loose and when i put any electrical load on turn signals,voltage dropped loww enought to kill the ecu and stall the engine.
