Question about the ECU....

[maximumgalant2]

Does the ECU need to re-learn again after disconnecting the battery?

reason I'm asking is i pulled the spark plug the second time again today, the first time i pulled it was about three months ago.

anyways, at both times, after i put it back together and drive it, i noticed that the rpm drops to about 300 to 400rpm when i am stopping.

so, if the answer is yes, how do i do it?


thanks.

btw...its a 2001 v6 es

Yes, the ecu does relearn after you disconnect the battery. The car will "learn" after 16 minutes of driving and 16 minutes of idle. You dont have to do it all at once. lol

yes and you should turn EVERY thing off inc: lean in window and press off button on A/C as you start the car, dont touch the throttle and let it idlefor 10 mins
