So another bit of fun. We're approaching 500k on the 240 and I suppose odd problems are to be expected. Today's adventure appears to be ignition related. Smooth running EXCEPT for the occasional stumble.
New:
COIL - BOSCH OEM
COIL harness spade connectors
CAP
ROTOR
POWER STAGE - BOSCH OEM
PLUG WIRES
PLUGS - NGK BPR6ES
When she's running at highway speed, it's just super smooth EXCEPT for what feels like random misfire, which can cluster or go for a few minutes without manifesting.
No lag or symptoms of fuel delivery issues.
No codes.
No correlation between heat/humidity and missing.
No worsening under load, but you do notice it more because the miss hits when you're needing acceleration.
Ideas?
