(Title has a silent ‘p’)
I finally had a reason to take the truck out after replacing the knock sensor a few days ago, and it ran just fine, so I think that’s solved.
The issue I’m focusing on now is that after it’s warmed up and the idle revs drop to ~700, it starts to idle roughly. It seems like it misses a step, the revs drop halfway to zero, then it catches back up. Often the stutters will be clustered a few seconds apart, but then it could fine for 10-30 seconds. Once it stalled itself (all the other times it’s stalled it’s been my fault).
It seems like a cylinder or two might be messed up? I haven’t really gotten around to inspecting inside the engine, so giving the plugs and distributor cap a look over is my next step.
