I got misfires and the engine light yesterday, a couple times.
The codes got deleted today on accident removing the jb4. I was going to take it to the dealer.

Do I need the codes to come back for the dealer to even bother looking into? (Maybe wait a day or two)
Or should I take it in asap? because I also have an oil leak starting to drip wherever I park.

Dealership won't touch anything if there isn't codes.... It's pretty easy to throw a misfire code during a third gear pull to redline if there is a problem.... Not that I recommend it

trace the oil leak, how many miles do you have and have you ever replaced the valve cover gasket?
