Hey guy's my battery died i put a new one in now it wont idle i tried reseting it didn't work not unless i did it wrong? I let it sit for a bit before connecting the new battery then when i turn the key everything on the dash lights up then there is just a t left where the odometer reading should be it doesn't go away so i turn the key off then start it it started it idled rough the idle got worse untill it died. I can start it keep the revs up theres nothing wrong its still smooth while revivng but take your foot off and she dies. Anyone pls help its driving me to drink.

same prob on my ef i6 done dignostic come back saying PCM was stuf,t havin,t got a new one yet but turned up idle scew on throtle bodie for short turm fix

take it for drive and get back to us.

i had a problem where the connection that screws on to the battery was loose and the car actually turned off while i was driving. i tightened it back up and it was idling rough. Took it to the mechanics and they said that if the connection comes off while the motor is running or it dies it can trip the computer and stuff up settings or something like that.

normal it need the base idle reset and some cars you can do maunaly but some you have to get a scan tool to do it to

More info needed. The extra time taken to replace the battery would have erased the KAM. Therefore it needs to re-adapt for a good idle.
Having said that it should idle pretty good without adapting unless something else has happened or changed that we don't know about?
