Computer reset problem!! PLease help! My car was throwing a low O2 sensor reading code making the car run rich. I unplugged the battery over night to clear the code and the next morning when I reconnected the battery and tried to start it the car wouldn't idle at all. This happened about 5 times and on the 6th time the car started and idled at very low RPMs. Now the car starts fine but it still idles at very low rpms (between 500-600rpms). Some times it seems like the car wants to kill. I did have a tune but did this reset the computer back to stock? Thanks guys

It's normal for the idle to be grumpy after resetting the PCM but should be OK after a few cycles. Resetting doesn't erase the tune, just the learned idle and readiness tests, etc. Did you take care of the 02 issue? 5-600 RPM in gear idle is normal if you have an A4.
