I need some help interpreting the problem. My car went into limp mode (check engine light went on) and idle is unstable (jumping from 1000 - 2000rpm). Goes 20mph and then jerks. Went to the dealer and got the following codes:

2002 C32

P2407 (ETC)
P2000 (ESM)

P2032-008 (Throttle valve actual value pot: line mixed up P0120)
P202E-008 (Throttle valve actuator: line mixed up/positioner fault P0120)
P20D4 (The load limit is active)
P203B (Fault of function monitor in electronic accelerator P0221)
P2050 (Misfiring P0300)
P2051 (Misfire cyl 1 P0301)
P2052 (Misfire cyl 4 P0304)
P2053 (Misfire cyl 3 P0303)
P2043 (Misfiring P0300)
P2044 (Misfire cyl 1 P0301)

My guess is that the throttle actuator went out, but could it be the MAS instead/as well? Any suggestions would be greatly appreciated. Thanks.

I have the same problem like yours. Did you manage to find out the problem?
Thanks

Same problem on my '02 for more than 5 times. Throttle actuator was replace 3 times, connectivity was checked on the throttle actuator wiring harness numerous times.

Do a search on the topic and someone got the problem fixed by replacing the traction control module....

My problem went away after the dealer replace the entire engine wiring harness,, keeping my fingers cross this time.

Yea, the throttle actuator was okay. The engine wiring harness was replaced but still does not connect very tightly or well. I decided to reinforced the connection by cable ties to keep it tight and from moving around. After that, I've had/heard of no problems since I sold the vehicle.
