I have a 1997 Buick Park Avenue, 130,000 miles, 3800 V-6, service engine is light on. Codes read by local parts house, three codes. MAP Sensor, MASS Air flow sensor, Throttle Positioning Sensor. Replaced the mass air flow and throttle positioning sensors and still shows issue on these items. All three codes said low input voltage....what could problem be?
