Been doing some searching and I'm hoping some with experience can help me out.
After sitting for a couple of months, I tried to start the WJ with no luck. It was the battery so I jumped it and got it running. It wouldn't hold idle but no codes where being thrown.
I took it for a nice long drive in hopes to get the battery charged up. I could start it but it still would not hold idle. Needless to say it was interesting going home when I hit the stop and go traffic part of my commute.
I know if the TPS is out of parameter, it will throw a code. I've read that the PCM has to "relearn" everything after a dead battery. The commute was 25 miles (one way) so I'm pretty sure it would have had to re-learn everything by then.
I've got no codes being thrown, what else could it be?
Thanks in advance!
