jeep liberty 2005 4x4 3.7 v6

got codes for a number 1 and 4 cylinder coil replaced all 6 of them and spark plugs...still replaced crank,cam,tps, cleaned TB, soon as it starts engine is missing shaking...put it in gear stops til i come to a stop then rough idle...get out on the road runs great til i get about 50-60 or try to smash the gas it bucks and speedometer needle jumps back and forth til i let up then it goes and have to ease back into it...

had it at dealer charged me 90$ to get me codes i already had...telling me they want to chase wires.... at 90$ a hour or replace pcm(but not sure its the issue)....anyway know what to try next...erased codes after i replaced the coils no check engine light but still messed up...almost seems like it maybe cata didnt get much smoke on seafoam wonder if it clogged?
