Another 94 E320 idle problem, HELP!!
 

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.

Change the 3 coil to plug connectors under each coil and put in a set of Bosch F8DC4 plugs.
Clear all codes and retry..

For pin's 8-14

PS Hey Arthur Dalton, where is the complete list of codes? In your head?

Looks loke maybe he put the wrong plugs in, they are Bosch RO-392. I am off to the dealer for the ones you listed.

All better, found one plug with a too small gap of about .005, runs great now. Thanks for your help.

Dan

Right where you found them.. in the Archieves ..
Let your fingers do the walking...

Is that a # on the insulator? That may be a date/production code ..
The plug # is stamped into the side of the metal hex base ...

Arthur, yes the plugs were correct but one had a closed gap, he must have dropped it. Runs perfect now.

Dan

He musta let one of the "Z-Techs " put the plugs in...

A friend of mine works at a Dealer and he mentioned the Z-Techs to me .. so, I asked , "What the hell is a Z Tech...?"
He said they are the guys that come up from re-con and Techs are rated from "A" to "Z' ....
