I think so, now it's jumping on first gear now, beside that all rest of the gear are fine. for the misfire i took the car to a mb tech and even them having hard time to solve the problem and i spent around $1400 and problem still no solve, so the tech is charging me for guessing i should of guess myself and i wouldn't spent that much. No one seems to have an idea what is causing the problem. I think i'll just junk the car or part it out.
