the other day i got a cel so i brought it into a family friends shop. i was having mis fires in cylinders 1,3, and 4. even though this happened the car ran fine and i could not notice any difference in driving. when i brought it in they checked the spark plugs and said it was fine, than he mentioned that maybe the injectors were dirty. but wat is even worse is that he did a vacume test and said that i may have a bent valve. i really do not know wat this means or how this could have happened if this is the problem.
for now he filled my tank and put a high concentrated liquid in the car to clean everything out. since than i have noticed the cars idle is rough and the turbo gague is sort of bouncing. anyone know wat the problem could be?
