The check engine light is on. on 2004 Chrysler PT Cruiser

A mechanic checked it for me and said it is telling him it is a missfire problem. I notice also, that the engine compartment is very hot - the hood is hot to the touch. The temp gauge is at the halfway mark

A misfire can be caused by engine mechanical issues due to low compression, it can be a fuel issue (bad fuel injector or vacuum leak) or it could be ignition related (spark plug, ignition coil or plug wire were applicable).P0300 is a general misfire code affecting one or more cylinders P0301 through P0304 identifies which particular cylinder is misfiring but tests need to be done to see where exactly the problem is. A "lean running" misfire condition can cause an engine to run hotter. And an engine that is running poorly because of a misfire can run hotter.

Thanks so much for this info! My mechanic is out of town til Monday so will see him then. I am going to print your reply for him to see. I did notice the light going on after most fill-ups of Costco gas. Wonder now if I am in trouble for always using regular when the car recommends premium... Anyway, thanks for your time trying to help me out!
