Happy to join the forum. I drove 4.5 hours to get this truck.

on the way home I noticed she was riding rough... then threw a code. Cylinder 1 misfire and throttle body position sensor. Well I was planning on doing a tune up anyway. Oil, filter, plugs and wires. I just added the TB position sensor.

plug for cylinder 8 is a PITA by the way... had to take off the wheel well cover to get it.

check out this plug for cylinder 1... hope this doesn't indicate a head gasket leak... or worse... water jacket.

all the other plugs were fine. I mean, they needed replaced, but didn't look like this.

Anyway, happy new year!
