1999 Ford Explorer 6 cyl Four Wheel Drive Automatic 150000 miles
I have a problem where while driving at a low speed with very little to no throttle, slowing down, or trying to stop, my RPMs will waver and drop. Sometimes the engine will stall. I will have to restart the engine while driving or stopped. Sometimes I can tap the brakes or gas and the RPMs will go back to normal. I have a code on the dash. I have pulled it. It talks about something running lean. This points to Mass Airflow Sensor. I have removed, cleaned, and reset the system twice now. The problem was temporarily fixed the first time. The problem got worse (aka happening on a regular basis now). I was wondering if there is a way to bypass or fix this problem, or if anyone knows what exactly is causing it. I might also have a bad catalytic converter. Could that be causing my problems. I greatly appreciate any assistance.
Thank you ahead of time!
have the same problem?
