Ok here we go, last week my 94 E320, 114k, started running like crap and I took it to an independent tech who said I needed coils and a wiring harness, I said Ok because of all the times I have read about it here. It fixed the miss under load but now I have an erratic idle he can't fix? I made The Dalton code reader and here is what I found, pin 8, codes 21, 22, 23, 24, & 47. Pin 14, code 2. Pin 7, code 1. Pin 6, code 8. I have been looking in the search area but can't find a code list, any help would be greatly appreciated.

Dan
