Truck was running fine just no OD. Went to start and the truck started rocking hard so i shut it off real quick. Now i have error codes 0129, 0645, 0688, 0571, 2108, 2174, 0539, 2106 and c-codes 2736, 2936, aa04, ab04, ac04. Any ideas? No key in the ignition and the instrument panel would light up and start dinging like the key was in, tap on some of the relays and that quit happening. Thinking it could be a computer issue? Can't hook a diagnostic tool up, not for sure why, just supports my believe that it is a computer issue. Just don't understand why my truck would have such a hard rock, felt like the engine was unbalanced and only one side was working(Don't c how that's possible, but you can better understand the shaking at least.)


I looked up some stuff about the codes, i simplified them.
0129 - MAP Sensor
0645 - A/C Clutch
0688 - ASD Relay issue
0571 - Cruise Control Malfunction
2108 - Throttle Actuator Control Module Performance
2174 - Low Airflow/Restriction detected
0539 - A/C Temp sensor
2106 - Throttle actuater assembly sensor

I have had problems with my ETC, but it wasn't causing problems as of recently.

If the PCM is bad, you have no open loop, no closed loop, no pre-programmed trims, no trims adjusted for sensors, no nuthin'. Could very well be the PCM...

If you determine that it's the PCM, I might have a source for them at like 1/3 dealer price that I found while researching for parts to over-haul the engine in my Grand Cherokee. PM me if you find you definitely need one, might be able to save you some $$$...
