computer??

Re: TJ exhaust crack advice
Not sure... when I replaced my manifold with a header, it idled a bit
high (1000-1100) for about a day until (I assume) the computer reset
itself. This was even after the battery had been disconnected during
the entire installation process. No check engine light for me though.

Re: TJ exhaust crack advice
hmm....well, I'm sure the computer 'keeps' memory with power failures. But
this was a much suggested way to get it to adjust faster....
