I have a 2000 Jeep Cherokee Classic xj 4x4 I was pulling a trailer the other day and it started skipping and hasn't stopped since and today I noticed the engine light will flash a few times then stops and goes off any ideas on what to do?

Also sometimes my ac will blow super cold when first start and once I start driving start blowing warm air

You probably cooked a spark plug or 2. I say more than one because your getting the emergency code due to multiple misfires.

Don't know about your A/C.

Low system voltage can also cause multiple cylinder misfires and a failure of the air conditioner compressor clutch to engage (it is an electromagnet). Having an additional load on the electrical system (like a trailer hookup) can bring some of these problems to the surface.

Scan for codes and look to see if there are Pending Codes.
