1993 Ford Ranger Q&A
1993 Ford Ranger Question: ck eng light comes on after truck surges, at stop lights.
Need more info. From what you posted I would suggest removing and cleaning the Master airflow sensor located about 6 inches from air filter. Need safety starheads to remove it. Otherwise, it could a fouled catalytic converter. But, need more info and get check engine code read if possible. Use master airflow cleaner only on the sensor. - csubak30
it doesn't happen all the time, just now and then.
