Jeep Erratic Idle
Hey Everyone,
I recently had a problem with my Jeep running very rich and not running
quite right. Well that was finally fixed last night when a hole in the
vacuum line to the M.A.P sensor was discovered. Went and started it up
for the first time since I fixed the vacuum line, and it fired up
quicker than normal and isn't running rich anymore, but now it has a
fluctuating idle. It will idle between 900 and 2,700 RPM now. If I
disconnect the M.A.P vacuum line, it goes back to how it used to be and
idles, but runs very richly. Does anyone know whats going on?
Thanks,
Gary

Re: Jeep Erratic Idle
You have another vacuum leak from those symptoms. Something like the
purge valve on the old style canister going bad would cause that or a
bad EGR.

Re: Jeep Erratic Idle
I wonder how the 02 sensor is after getting hit with all of that rich
exhaust.
