all the time now.
2008 honda rigeline is not firing on cylinders 1,2,4 and 6...why and what should on 2008 Honda Ridgeline
Does it run? (possibly bent valves) but lets keep it simple. clear the dtc's and start the car if it runs and read the first dtc that pops up? Swap coil packs around. see if the dtc changes.
How many miles on it? Have you pulled plugs and inspected for oil fouling? Did all 4 cyl. start misfiring at the same time or was it gradual?
