Working on my friends truck and I'm getting only a cylinder #7 misfire DTC. I can feel the engine chugging and misfiring intermittently on acceleration. I've changed the spark plugs and looked ok. Compression on all cylinders seem normal. I'm gonna try swapping ignition coils next. If not, thinking then it might be the injector that needs to be replaced. Need to know which cylinder is what before I can make any further diagnosis. Any info would be very helpful, thanks!
