In need of some help
I have a 2007 C-280 with about 70k miles on it. I just recently did an oil change and right after the car has been acting up.
1) Rough idle
2) A bit of loss of power
3) And today, there was white smoke at start-up and it took a while to kick over when i started.
I had a check engine that came on, but then it turns off (this has been happening for the past 6 months now). Went to Autozone and the readout is
P0302.
I'm replacing the fuel filter tomorrow, but I have a feeling the o-ring might be missing when the tech did the oil change, plus I figured I need to change the spark plugs..
Anything else I need to do? is it safe to drive w/o the o-ring??
Search the forum or google and you will find a solution. I typed "w203 P0302" into google and got a bunch of results.
Cylinder 2 misfire could be due to bad spark plug, coil pack (likely), or ignition wire. To narrow down the culprit, swap the coil pack/wires with neighboring coil pack/wire and see if the problem code changes.
