Hello, my name is***** means cylinder 3 is misfiring. Does check engine light ever flash while driving? Thanks.

( NO ) plug Heater shows as 2nd problem.
Expert:  Dan replied 2 years ago.
There is no component called a plug heater. If getting a P after the code that usually means scan tool is tell you code is pending. So this code would only be related to the cylinder 3 misfire. Does check engine light flash?

Have you tested for spark on cylinder 3? If not, that is your best next step to determine if you have a weak coil.
