Bought this 06 about a year ago with 120,000 miles. Didn't have any whine. 10,000 miles later a timing chain tentioner failed. I replaced all three tentioners along with the larger of the three chains. also replace plugs and water pump while I was in there. All put back together and it's missing on one cylinder:cussing:. Now I'm like:dontknow:. My thoughts are coil, plug, bent valve. Anyone know what the likely culprit might be?

Do you have the code itself? The reader may not tell you which one, but the code itself can.

This.

P0300 - Random misfire (this code sets first, as the ECM hasn't had yet identified the specific cylinder, P301-P0306 sets next.)
P0301 - Misfire cylinder #1
P0302 - Misfire cylinder #2
P0303 - Misfire cylinder #3
P0304 - Misfire cylinder #4
P0305 - Misfire cylinder #5
P0306 - Misfire cylinder #6

ECM was throwing the 300 code for random cylinder. I've pulled the spark plugs again and am going to do a compression test on all cylinders to rule out bent valve. Chiltons says the fuel pump fuse is the passenger compartment fuse panel. None of the labels there say fuel pump. Do you know how they have that one labeled?
