Erratic idling and engine stalls 200000miles new maf fuel filter air filter just about to check idle control valve can anyone advice me on how to clean properly and if it could something else plz ......... thanks
Fault code p0171 suggesting air leak also code p0170 could be throttle body, crankcase breather o2 sensor.
At first it was only erratic idling on cold but it now even when hot and occationally it stalls on hot and cold engine. looked for air leaks but after a good inspection found nothing. any other ideas. thanks.
