The Check Engine Light came on and initially indicated a bad Air Flow Sensor. Changed it and at first appeared to have solved the problem.
Symptoms are; it fluctuates at idle and bogs slightly at takeoff. No power loss or lost fuel economy. Problem seems more pronounced after the engine gets to normal operating temp.
OBD Codes indicates "too lean" fuel trim at limit. Occasionally, a bad EGR Valve and lack of O2.
Any suggestions?????
