I know, I know I was in another thread singing the praises of the Chinese built 3400 but OMG does this motor suck. I mean sure its got plenty of power to motivate my van.
But lately I have been having some major problems. Take this for instance after getting up to highway speed 65 - 70 and after attempting a pass the motor seems to start to "limp" and the service engine soon light started to flash and it varied with engine speed how fast it blinked sounds and feels like only three cylinders are working. After pullin over and coming to a stop the motor seems to rock the van extremely violently and a stong smell of buring rubber entered the cabin. I cut the motor off and started it back up five or six minutes later and the problem was gone but no soon as i got back to 65 it did it again.
What could it be I've takin it to the dealer and they couldn't get it to do it. But upon leaving the dealer it did it when i merged into traffic so i brought it back and they felt it and they cut it off so they could check for trouble codes but when they turned it on it wouldn't do it and no trouble codes were tripped I'm not sure what else it could be. Any thoughts on what could be wrong. It seems to be ok jus driving around the city.
