Hey everyone.
Since i got the car in August it has had a rough idle. We took it to the dealer and had them replace all the plugs and clean the fuel injectors. After that the car ran a bit better but still had a rough idle.
Now, the check engine light has come on and it is idling very rough, like when we first bought it. I'm not sure what the deal is. Its throwing a p0306 code which I read is a mis-fire in cylinder 6.
I am wondering if the dealer actually changed all of the spark plugs or just decided to do the first 4 because the last 2 are difficult to get to. I think i may have to try to pull the plug out myself to see if they actually did change them. Other than that, I'm not sure what it could be. Any ideas?
P.S. The car is difficult to start while warm and is rough until about 1.5k rpm's and during idle where the needle fluctuates a bit and the car shakes.
P.S.S. Anyone local around Boston who would not mind earning a few bucks and knows how to change the plugs?
