2005 DCLB 134,500miles
The other day I went to start my truck with the remote start, about 25* in the morning here in Jersey and have to bring my 3 yr old to preschool. So I warm my truck up a bit so it is warm for her. The truck didn't start the first time so I tried again no luck.
So I went out and got it to start with probably the last bit of battery life so I thought. Went to preschool then to work about an 1hr driving, then 45 minute back home that night and went straight to advance auto to have the battery and alternator checked. Both checked out fine. Then this morning the check engine light came on. Back to advance after work to have the code checked it came back with P0306 Cylinder 6 Misfire Detected. I change my plugs every 30k miles and cleaned the throttle body about 10k miles ago, oil changes every 5k with mobil1 and factory filter. So is this a fluke? Anyone else have this problem? Guy at advance said to do a tune up, not that he is any kind of mechanic. Any thoughts?
