C350 Sport "Misfire P0302" code
Hi everyone! I am fairly new to the MB world.. I purchased my beautiful 2009 MB C350 Sport last July and have really enjoyed driving since then
Although, recently my car has been riding a little differently(hesitates when accelerating, sounds funny when idling).. Just a couple days ago, my car started up and was smoking under the hood. It was shaky during idle and the check engine light started flashing. Of course, I immediately turned my car off and have not driven it. It was about due for an oil change and my fiance was worried with the symptoms, it could be a blown head. He changed the oil and thought it looked fine(no evidence of coolant spilling).
Today, I bought an ODT II sensor and the code came up as "Misfire, P0302, Mil on monitors 0 inc, 9 ready, Misfire fuel comp catalyst evap, sec air, O2 sensor, O2 HTR, EGR"... Anyway, I googled the main code, P0302, and it came back with a variety of things:
-faulty spark plug 2
-clogged/faulty fuel injector 2
-faulty ignition coil
-fuel injector 2 harness open or shorted
-fuel injector 2 poor electrical connection
-ignition coil 2 harness open or shorted
-ignition coil 2 circuit poor electrical connection
-insufficient cylinder 2 compression
-incorrect fuel pressure
-intake air leak
I am really worried with the amount of money I'll have to spend trying to even figure what is wrong with my car, not to mention--actually fix it.. Has anyone else had this code or a similar code?
I would really appreciate any insight/advice! Thank you!!!
