My Jeep is throwing a P0304 Check Engine code, making a clattering noise from the driver’s side cylinder head, and is idling rough.
Yeppers, burnt exhaust valve on the #4 cylinder, a common problem with the 2012 Jeep Wrangler. Luckily Fiat-Chrysler extended the warranty to 10 years and 150,000 miles on that cylinder head.
So now you know what I’ve been busy with tonight — rounding up paperwork and making sure my Jeep is in order to take it in to the dealership tomorrow.
