check engine light blinks while driving
Check engine light blinks while driving but don't feel like it effects how
it's running , also not firering right on number 7 cylinder comes and goes
A flashing check engine light is telling you the engine is misfiring and damaging the catalytic converter. Since you know something is going on with cylinder number 7 start there. That's most likely what's triggering the check engine light. Are you due for a tune up? HTH. - Jim
Sparkplug, plug wire (if equipped) or bad coil on plug (if equipped) are the likely causes. When were the sparkplugs last changed? How many miles on this F-150?
