if thats what your thinkin, you need to reset your ECU and have your car idle for about 10 minutes. so the ECU can readjust

mine does that for awhile after the ecu gets reset, which is what happens if your battery dies.

yeah i tightened the battery to the best of my ability. i guess the ecu is just trying to re learn the idle point. i hope it'll get better within the next few days.

If your car is OBD-2, you will need to run the idle learn routine.

Step 1: With the car totally cold, start it, then hold it at 3000 rpm until full operating temp (radiator fan will cycle).

Step 2: Let the car idle with all of the accessories off for at least five minutes. If the radiator fan comes on, add it's run time to the minimum 5 minute idle time.

Basically let it idle for 10 minutes with the accessories off and you should be set.
