my son broke down last nite in his 2000 cherokee.
it died and wouldnt start as he was driving.
we pushed it into a lot and found that a vacuum line had popped off on the intake just below the throttle body.
i found it on the ground right where it originally died and it started once put on again but you had to keep the rpms way up.
everytime it tried to start again it acted like the timing was way off and popped and backfired but eventually started as long as you kepth the rpms way up.if you tried to let it idle it died right away.sometimes if it backfired it would pop thart vac elbow off again.
the muffler looked destroyed and we thought it was blocked inside so we sawzalled it off and i think that was the problem.
it runs and idles but idles poorly.
we thought maybe the cat was cloged or broken inside so he decided to cut that too as he is going to just get a whole new system put on.
it runs and wont stall but seems rough and the chk eng light is flashing like it sees a major problem.
we cut this all pretty far after the only oxygen sensor.
do you think the chk eng light is blinking because it senses no cat?
he is getting a new exhaust put on today and im just wondering if i need to do more work to fix the problem.
