What would you make of these codes? Multiple engine codes on 2001 C240
Im trying to figure out this 2001 c240. Maybe someone here has had a similar experience with their car?
The car runs poorly when warm. When accelerating, the car hesitates. If i keep my foot on the gas the car will eventually get up to speed, but it is not smooth. Often when the car is warm and i come to a stop light, the car will stumble and die. If i try to restart, the car will restart, but then is sluggish taking off again. CEL is on. Codes are 1.Random misfire detected 2.Fuel trim bank 2 3.Cylinder 1 misfire detected 4.Cylinder 2 misfire detected 5.Cylinder 3 misfire detected 6.Mass or volume air circuit 7.Fuel trim bank 1 I have already checked the fuel pressure and it seems to be holding strong at 55lbs. Does anybody have any Ideas??? Thanks in advance for your input! Last edited by benjay; 05-13-2011 at 02:30 PM. |

Sounds like a mass air flow sensor issue, very common problem.
