1996 jeep cherokee stalls, I've replaced the throttle position sensor, MAP sensor, and carbeurotor. What else could it be?

clogged catylitic convertor

definately a vacuum problem, try changing your pvc valve its under $5.00 and easy

code p 0122 causes are wiring short to ground , TP/APP sensor --ECM
or also wiring open/ short to ground / short to positive TP/APP---ECm
so check the wiring and connections
code p 0107 is map and /or BARO sensor --low input===causes ---wiring short to ground ---MAP sensor ---BARO sensor--ECM

I would change the TPS throttle position sensor and the Map/MAF are you sure its not the mass air flow?. I think your computer is fine it could be have a loose ground issues but computers dont go bad.

Your timing is locked. (distributor is installed with no adjustment feature... on 02's you may not even have a distributor as it's replaced by the cam sensor) All timing and fuel mixture is controlled by the engine computer. Main inputs to the computer that influence changes are the throttle position sensor and MAP sensor but all sensor inputs are evaluated.

on the drivers side if you look straight down in between the intake and the firewall you will see it bolted to the transmission. The harness plug in is in that same area as well.

check the crank position sensor and the throttle position sensor

Sounds a whole lot like a dirty or malfuncitionig idle air control valve. A coil would generally show up as a miss under load or high rpm, crank sensors generally work or they dont, only sometimes giving you a miss, but that would be all the time at any rpm. Computer, I doubt for too many reasons to list. Could also be related to a bad throttle position sensor or a very slight vacuum leak.

Does this thing have a throttle body that looks like a computer-controlled carburetor?

If so, start motor and verify that it behaves irratically and then stalls.

then, spray WD-40 liberally around base of throttle body where tb meets intake manifold.

Start motor...

Does the problem go away, at least whilst for a little while?

Yes?

You gotta vacuum leak. Replace gasket under TB and tighten bolts to factory spec.

I HAD THE same problem.... 87,000 2000 grand cherokee 4.7l
when i let off the gas it might stall. happens 1 to 4 times a day.
so far i have
replaced the crank shaft sensor - it stopped stalling for 3 days $130
cleaned the throttle boddy free
replaced the throttle position sensor $72
replaced the idle air control sensor $132
replaced the map manafold airflow sensor $125
no luck it is still stalling. by the way i have done all the work myself. it was about 30 minutes for most parts
i just ordered a rebuilt ecu or pcu engine control unit. they program in the vin, mileage and part nbr so you gc will recognize it. $185
installed ECU 2 days ago...... so far so good.
good luck
