On my 95 D1. I've read all the info on stepper motor issues... I've cleaned, tested and cleaned and tested. Ended up replacing the stepper motor because the ECU is absolutely determined that it's a problem. I've reset the codes, it comes right back with the warning lamp on the dash. Had a dealer look at it and they said they have no clue why and suggested a new ECU, they'd be more than happy to sell me one (I think they're just making excuses).
Truck actually runs great! Smooth idle, plenty of power and fuel economy better than many other D1's. Problem is that the emissions testing station won't pass it with the CEL on. I can't disable the lamp because they check for it on startup... What kills me is the truck PASSES the sniffer test with flying colors!
Suggestions?
