Are any of the check engine lights on. This happened to me with my kids in the truck, it just died and I lost power to the steering and all. I turned the key and bam back up and running. My check engine light is on and the guy that owned the truck before me said they diagnosed it with carbon build up. How can I fix the carbon build up. Thanks and btw I have a 2005 ram 1500 5.7 hemi it has 86,000 miles
New PCV for sure, run a group 4 or 5 synthetic, this will help clean the bottom end. Just having a new PVC and any oil will clean out gunk build up, but ester based oil will clean better. On the top end I'd try Red Line SI-1 Complete Fuel System Cleaner, marvelous mystery oil, lucas upper cylinder lube, techron, all in your gas only none in crankcase. I would run a different one every tank and see if it helps. Redline is high end synthetic detergent, techron is a combo solvent, MMO is a napethenic solvent and added lubrication, and Lucas is just lubrication. The problem is not unique, this Ethanol in our gas is killing engines. Google ethanol damage and you likely have some of the same stuff going on. You need both different cleaners and lubrication, MMO and Lucas can be put in every tank and they are dirt cheap by the gallon. I'd run 8 ounces of both for a while with the techron, try redline too.
