1998 Ford F150 V8 Four Wheel Drive 160k miles
My 1998 ford f150 started running really rough today and the check engine light started flashing. I took it to have the error codes read was told that the following error codes registerd on the computer: p0307 cylinder misfire detected cylinder number 7, p0401 Egr system fault, and p1151 accelerator position sensor aps property malfunction. The worker at Autozone said it was either the Mass airflow sensor, the Egr valve, Bad spark pugs or Bad wires. From you experience what should I replace first and what is most likely causing the truck to run rough?L
have the same problem?
