Precursor to current issue. Went driving in NC mountains in sept, dropped fire to cylinder 4. Turned out to be leaky spark plug tube, shorted out plug and coil. Borrowed space in friends shop and pulled engine for new seals on both valve covers/tube seals. New plugs too. Put 200 miles on engine and notice a tick on exit ramp. Putt the car 20 miles up the road to parents and read current codes P0301, P219A, P119F, P119E. No longer ticking, rough idle, exhaust smells rich. Cylinder one actually has the new coil pack now, unplugged and reinstalled coil plug, pcv lines attached, brake booster attached. I only have top two DI computer bolts installed and read somewhere all 3 need to be installed for correct grounding. Any ideas?? I’m a noob to a lot, as well as code reading. How can I diagnose this? Valve rockers were all in place and cams looked good.
