i posted a whiel back asking for help on why my friends 01 3.9 was missing and runnign bad. well we went ahead and did wires and put better sparkp plugs then what the dealer put in about 3000 miles ago and the problems stayed the same. so he took it into the the dealership and at first they didnt fell anything, these authorized dodge dealer mechanics couldnt feel a damn miss so my firend had to dirv eover there and show them. so then they call him back later that day and say well the plugs ans wires and different then what we use so im gonna try plugs, wires and cap and rotor, the exact same thing THEY did 3000 miles ago. is it just me or dealerships getting stupid and cheap on people that have warrantys. my firend didnt know a lot about cars an dive taught him some things so instead of just trying to rip him off he knew what he was doin. ive heard tha tit can be timing or injectors or a bad distributor. i just cant believe how stupid dealers are! if u guys know of any common probs of why they miss then please let me know.
