Just seen the little clip on top that you got to push down before you unplug coil pack.

 

UPDATE on the p0304 and p0300 trouble codes:

New NGK plugs are in, hesitation (misfire) seems to be gone as I drove around the block fine and she idled in the driveway fine. Have to clear the code now. Thanks again chambers.

edit. Plugs looked horrible, gap was easily 2.5 times the proper spacing.

 

Glad I could help. Pulling the neg. battery cable for 10-15 mins. and then reconnecting it should clear the codes then just drive and hope they don't come back.

 

NGK Iridums here too. Love them. For me the back driver side plug was the hardest to pull. Got a ladder for a little support (had my feet on the ladder and knees on the bumper.)

 

Started truck this morning and the diagnostic symbol was gone. Turned the key 5 times in 5 secs and the code is not showing anymore. Hopefully this was the problem. Drove 90 miles today, took the kids to hockey and all is still well.

 

I got a good stretch on the old calfs leaning in I tell ya.

 

Lol....

 

Personally, I would recommend NGK platinums at the very least. Me, I'm running around with a set of E3s. Seem to work pretty good in my opinion.

 

I had to move the brake booster out of the way.
