1992 Ford Aerostar XL
I bought a 1992 Ford Aerostar XL with 43,000 miles. I'm not a mechanic or very mechanically inclined. T he engine stated running loud. So I'm asking for help with some codes from the OBD reader I used on the van. I'm getting 157 181 185 186 and 121.
The manual says mass air flow sensor below normal . I removed and cleaned the sensor. The 186 code says "Fault in injector pulse width circuit/high" I don't know what to do for that one. Or the others. Any suggestions?
