got a check engine light problem...comes on when ever it gets wet...no other
probs...98 tj, 50,000 miles, 02 sensors good, got a catalytic converter
problem but that isnt it. I had to get jersey inpection this month. Dude i
know at my fav texaco did the inspection and pressure checked the gas
cap...all good. check engine light comes on whenever it rains or if the dash
gets wet...he said he "reset the ecm"....all was good for a couple
days..passed the inspection no probs...rained out...check engine light came
on...how do i reset the ecm myself....is there a switch or fuse or
something? thanks....
