Recently my 96 cherokee sport 4L 6CYL stopped running while taking a right turn. Replaced the Cranckshaft Postion Sensor, Coil, 30amp Fuse and my ASD relay (Fuse and relay were the problem). Now that she's running again the motor is almost stalling out in idle... My exhaust manifold is cracked and i am waiting tell next weekend to replace it. Am i getting low rpm's due to my exhaust manifold or do i have an electrical problem? I was reading on another post about Flashing the PCM. From my understanding that would mean erasing and reprogramming the PCM with new software. Is this something i should look into doing?

Thanks for reading!

 

Get the manifold fixed before doing anything else. That could very well be what's causing it

 

I agree, I had a leak in the exhaust at the rear of the motor at the head and it ran like crap some of the time.
I believe it is due to the O2 sensors getting wrong readings

 

Ugh, PCM if ya have to. Check o2's first, they are notorious for failing and will cause rough, low idle conditions.. Does it starve for air at any point? Like does it start sucking air hard when at idle? Have you dropped the tank and taken a look for swag in the tank?

Edit- missed the "cracked manifold" in OP's first post.. Oops.. Either way, get that taken care of and if issue persists then the o2's and the TPS is worth checking...

 

Thanks for the suggestions! Is there a way to test my Co2 sensor?
