Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello, my name is***** the check engine light flashes it means vehicle is misfiring, it usually means you have a failed coil. Lets start by checking diagnostic codes, here is a video that shows how to check codes. Let me know what they are, thanks.
It is usually pretty easy and I would expect repair to be around $200 at a shop assuming problem is the coil. Were you able to check diagnostic codes? Thanks.
Checking codes is going to be needed for me to give the best answer possible, you can check them yourself by turning key on-of-on-off-on and they will display on odometer as shown in above link. Let me know how it goes, thanks.
You can also have codes checked at your local parts store for free which is probably your 2nd best option. Let me know what codes you are getting when you get a chance to check them. Thanks.
