I'm Ben, I am new to the forum. I bought a '99 TJ at the beginning of the summer, it has run well, hasn't given me any problems. My one issue is that the revs will hang up around a grand or so when idling occasionally and on start up, I just rev it a little and it dies back down to where it should be, around seven or eight hundred rpm.
I was hoping someone would have any ideas to why it is doing this? Is it common problem? Don't know if it matters but it is a '99 2.5L manual trans.
