Q: Check Engine light comes on and off depending on the weather. 1997 Ford Mustang

asked by on

Hi...I have a 1997 Ford Mustang. The Check engine light comes on and off depending on the weather. The Ford dealership said the code that comes up is: P0302.
My car has a manual transmission.

Hello - the P0302 is a misfire on cylinder 2. The misfire on this cylinder could be a weak coil pack, or plug wire (oil contamination applies here), or a spark plug with a gap that is a bit too wide. Since it is weather sensitive, could also be an injector that is dirty and not spraying properly as well. I recommend a misfire inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
