94 Deville Codes 4.9
When I first start my car and let it idle the service engine soon lite comes on. If I take the car for a drive and shut it off then start it back up the lite is gone. I have replaced the Idle control motor,Map sensor,both o2 sensors,sparkplugs&wires. When retreiving the codes I get P031,R060,R061. All are showing history. I tried unhooking the battery neg. cable but the lite comes back. The car run's great but this service engine lite is driving me nut's. Any help would be appreciated, thanks
