So, late last night after a full day of driving around aimlessly I parked in my garage. 3hours later I decided I decided I was hungry so I went to start my car and my CEL came on. This morning I went and got the code read, and it said P0305- Cylinder 5 misfire, now I'm pissed... I just went to Napa near my house and had to order a new spark plug(apparently nobody carries ones for MB).. So now I'm sitting at dunkin waiting for them to come in. Has anybody else had this problem, I really hope changing the spark plug will fix it

 

O and btw I don't notice anything wrong w the car

 

It could be a spark plug, it could be a coil pack.

 

i hope so lol, im going to replace the spark plug when it comes in and ill let u guys know

 

Sorry to hear that. Definitely report back when you change the plug.

 

hopefully it'll just be the spark plug and nothing else.

 

no go with the spark plug, still misfiring

 

Move the coil to another cylinder to see if the misfire moves.

 

i cleared the code and nothing seems to be wrong i drove around for about 15miles, the car seems to be working fine

 

Glad to hear, hope it stays like that for you.

 

Weird. Glad to hear it's working fine, but i would get it checked out to be on the safe side.

 

yea im going to go check it out tomm

 

Cool, be sure to report back.

 

Classic EuroGremlin.

 

CEL just came back on, and it read cylinder 6 so the problem is the coil pack. I just ordered it, it should be here in 2days!

 

Good luck, keep us posted.

 

prob fixed it was the coil pack

 

somehow napa autoparts had it in stock

 

Good job.

 

Glad to hear it got resolved. I chased that multiple misfire P300 gremlin in the ML430. Even after replacing plugs and coils it would just randomly reappear.
