Hello, my name is***** the check engine light ever flash? Did cooling fan start running at full speed after check engine light came on? Thanks.
The check engine light flashes too?
All of these things would happen due to the misfire. If the check engine light is flashing that means misfire is most likely caused by a failed ignition coil which is a common problem on these vehicles. Engine being overheated may have caused coil to get hot and fail which can happen. The coil is about a 3 hour job to replace and $60 part so you are looking at around $350 to have this repair done at a shop. I can give you replacement instructions if it is something you want to do yourself. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
Most likely because the misfire can cause engine to run hot so taking care of misfire is the first step you will want to take. Let me know how if you have more questions or if there is anything else I can do to help. Thanks.
