No I used gdi intake valve cleaner and finished with a can of gumout carb cleaner I just made sure that the valves were seated so nothing could get down inside and I used a little syringe to get all of the wet/broke down carbon/carb cleaner out and wiped with a dry paper towel. Still a lot of white smoke on startup after this procedure but once all of the solvent gets burned no smoke. But with proper maintenance this wouldn’t even have happened. This is why boys and girls you don’t drive with a misfire for very long

Yeah it fixed it for the most part, definetly not something I thought was regular Maintenance, still getting the misfire every now and then I think I may still need to give it one more cleaning or run a few tanks of premium through it. Before I cleaned the valves it was a dead miss so it’s definitely drivable now

So I bought a 2012 Dodge Journey a few weeks ago from a guy and noticed it had a misfire from cylinder 6(unclear how long it had been getting drove that way, but it must have been a long time) well anyways there was carbon build up on the valves and I’m guessing where cylinder 6 wasn’t burning the fuel that was coming in it liquified the carbon and turned it into sludge and the valves were pushing the sludge into the combustion chamber fouling up the plugs. I cleaned the valves with carb cleaner wiped it all down good and put it back together. Has anyone ever seen this happen before because it’s a first for me
