My check engine light came on while he was experiencing his bout with the tick of death. It was oxygen sensor and EGR valve associated. I've since put a new oil pump in and all new seals and the T.O.D. is gone and Ben is happy again. However he still has a CEL. (Code 34)
I've taken the EGR valve off and blown out / vacummed the intake passages on both the manifold and the valve itself. Not too much soot in there, but a bit. I reinstalled the egr and tested it. At idle, if I push in the EGR the engine starts fluttering, so I know that the valve itself is okay, correct?
I've tried clearing the CEL by connecting both green and white connectors under the hood. With the engine running with these connectors both connected, my CEL is OFF. I let it run quite awhile like this. Disconnected them and the CEL is back on with a vengance.
No matter what I do, I can't get the light to go off. I checked what codes are thrown in every combination of connectors with the car running and not running with the ignition on. They are as follows:
Both connected: code 7 (which is not listed in the USRM)
White connected only: code 34
Green connected only: code 7
Neither connected: code 34
Car not running ignition on:
I'm at a loss =\ any help guys?
BTW for those not familiar with Ben he is a SPFI 93 Loyale
