1994 Oldsmobile Achieva 4 cyl Front Wheel Drive Automatic 150000 miles
Hi. This car seems to be running fine, but the check engine light is on. I scanned it for codes and received 027 (quad driver b fault) and 035 (idle control valve not seeing rpm). I have replaced the idle control valve and ecm module. When codes are cleared, they return within 20 seconds of re-starting car. Sometimes only one of the codes will pop up, sometimes both do. Any suggestions?
have the same problem?
