MAP Sensor???? Running Lean???
My 1987 F150 is having issues when running under a load. AT about 45-50 mph or going up hill, the engine sputters and lurches as if it is not getting enough fuel. At first I thought this lean condition was caused by a clogged fuel filter or bad gas, but after changing the filter, cleaning the injectors, and filling up with new gas, nothing has worked. I suspect it may be caused by a fouled Mass Airflow sensor. Any idea if I may be on the right track?
I have the v6 engine.
