OK I just put in new plugs and wires about 2,000 miles ago Know I have a slight vibration in the engine Know I know that I'm a mechanic but I had but things with champon plugs so I put in Bosch Double Platium plugs now this problem does happen all the time a ichecked for the intake leak and nothing, I was talking to the dealer and he said that dodges love to run on Champon plugs, I also know that if your car didn't come with platium plug don't put them in ,I took out platium plugs so I put in a better platium ( SO I THOUGHT I WAS) What plug to you use in your trep.

I changed to regular Bosch platinums about a month ago (I don’t have personal experience with the new dual tip platinums). I just bought some Champions (premium golds) and will be putting them in this weekend. When I switched to the regular platinums, I almost immediately noticed an increase in misfire rate, and a corresponding rougher idle.

Put you ear close to the tail pipe (not too close :tongue: ). If you hear more than one or two misfires within 10 sec, I’m guessing your plugs are causing your grief. Don’t get me wrong--all cars misfire to some extent--I just noticed an increase in misfires when I switched to regular Bosch platinums.

Ravage you're using the platinums without any problems?? because i would like to change my plugs and i was wondering what to do for the 3.3L since we can't get the GOLDS...(wish i could just drop a 3.5 in )
