If anyone can help I would appreciate it. I have a 2002 Volvo S40 with 111,978 miles on it. I recently replaced my MAF sensor and started to get engine codes PO101,PO102, and PO172. The car idles rough and will stall after some time of idling. Air filter is brand new, and the throttle body is clean. Clearing the codes with a scanner doesn't help, the codes come back immediately. Anyone have a suggestions to diagnose the problem?
