Check Engine Light
Ford F-150

I have a Ford f-150 truck the engine has a miss to it and the check engine is on and then it blinks and then it stays on and at low rpms it runs rough?

I just got my f-150 fixed with that same problem. I replaced the

spark plugs and spark plug wires. The blinking check engine light

is caused by excess gas coating the catalytic converter sensor. If

left unfixed this will cause permanent damage to the catalytic

converter.
