so i went to the dealership and got some Mopar Combustion Chamber Cleaner, for after my plenum fix, i did not change/gut the cat.

went by the directions, and when i went to start it after the MCCC sat in the engine, to my surprise, there was no white smoke. after about 2-3 minutes she started a smoke show. i believe this is because the cat is gunked with oil residue.

Then i took her for a ride, and wow. this stuff really did make a noticable difference. Im not just saying this either. the pick up is alot better, the steady rpm ride is smooth as hell, and before when it idled it had a very very very very small putter that it would do. now it idles smooth n clean, nice and quite (aside from my exhaust)

All in all i would just like to recommend this to everyone, or those who havent used it yet. and for only 7.50 a can at the dealership you cant go wrong.

 

you put in gas ?? seems like seafoam but with a differant name

 

nope all you do is remove air breather, start truck, spray in the TB. Open the butterflies slowly and add contents.(its a spray can with a straw like wd40) it will try to stall out but dont let it. but dont go to excessive with the RPM's, 1700 rpm max. once the entire can is in, shut the truck off for about ten minutes. Start it and let it run for 5-10 minutes so it can get rid of all the residue. (smoke show)

Put it all back together and enjoy a nice ride.

 

I've read alot of threads in which people either recommend MCCC or Seafoam. They both do the same thing so either way, your safe.
