Hey All,
I just picked up a 88 YJ, The guy just put a new engine in it. It was having problems staying running at stop lights. It would start when it was cold no problem, but if it was warm it wouldn't start and i would have to pour fuel in the TBI and it would start. So i put a new fuel pump in it and that didn't work. So then I thought it might be a timing issue..i ran a timming light on it and it was pretty far off. so then i tried to adjust the distributor...it can't be adjusted. So then i reset the distributor back to top dead center..now it runs but the tach is all over the place and it won't idle consistant enough to run a timing light on it. it'll idle for a few seconds..then it acts like it wants to die and when it does that the tach pegs to 7000rpm...im scratching my head any ideas on what it might be??
