Misfire issue
when i start my car it runs fine, about 2 minutes later it runs really ruff misfiring really bad. The car will shortly after that run fine, then misfire again, then run fine, and after about 5 minutes it will just run fine until i turn the car off and start it again, then the process repeats itself. Now its taking longer and longer for the car to go back to running fine again. I just need some guidance on what to check first. My SES does blink when its running ruff. I checked all my plug wires and they seem to be fine(the spark plugs and wires are less than a year old). Could this be an oxygen sensor issue?
Any help would be appreciated
I had a terrible misfire issue that was caused by a spark plug. I must have tapped it on something while changing plugs
