Q: Is it safe to drive with a misfiring cylinder?

asked by on

My check engine light came on today, and the code stated that cylinder one was misfiring. However, I have not noticed any loss in power, decrease in fuel economy, or anything else that would indicate a misfiring cylinder, other than the indicator light itself. I haven't noticed any other issues, but I was planning on driving pretty far this weekend on a road trip with my Jeep. Am I safe to drive or should I get it checked out by a mechanic first?

My car has 7000 miles.
My car has an automatic transmission.

Hey there, thanks for writing in about your Jeep Wrangler. I would recommend getting it checked before going away on your trip. The misfire code may be a problem with the variable valve system or the ignition system. With this code a misfire may damage a catalyst.
