Hi all, I'm looking for some help. I tried searching, but maybe I didn't use the correct terms because i didn't get any applicable previous posts.

My 1994 E320 has an occasional issue with a power surging. When this happens, it feels like a bad fuel pump or clogged filter or cat. When it happens, the car will idle perfectly and run smoothly up to 1500rpm, then it bucks like a bronco! If you turn the car off and restart it runs just fine. Codes ( I don't remember which ones it threw and I don't have the car with me just now) point to the TA (CC/ISC module) and that the car is in limp home mode. The wiring harness is pristine, but I haven't checked the wires to the TA yet. If I clear the codes the problem will return, go into limp mode and run okay until I clear the codes again. The car does not have ASR. I am planning to pull the TA this weekend and rewire if necessary, but any ideas as to other avenues to look at would be appreciated./

Thanks
Greg
