I swapped one of the other ignition coils for cylinder 1's and took it out for a drive. I floored it up and down the highway and felt some hesitation, but not as much as before and I didn't get any DTCs.
I haven't really messed around with the engine other than the spark plugs and ignition coils. How would I go about cleaning the intake valves? I know I have to remove the air intake manifold. What else would I need to do?
