Well this one has me stumped!
Left work the other day. Car starts fine, get about 5 minutes down the road and I developed an obvious misfire. Pull off the side of the road, check to make sure everything obvious is connected. Everything looked fine. I was 16 hours into that day and really needed to make it to urgent care so I shut the hood and babied her to the doctors office. No problems other than running on 3 cylinders. Every once in a while it felt like that cylinder would come back online but only for a split second.
Get done at the doctor. Fires up fine (still on 3 cylinders) drive home. Pull one plug wire at a time to see if I can find the affected cylinder. The cylinder 2nd from the distributor cap when pulled had no change to the way the engine performed. So I did the simple thing and changed that one spark plug with a new NGK standard plug. From that point it started running worse.
For what it’s worth, every spark plug wire I pulled gave out a nice strong looking spark while the engine was running.
By the time I was able to move it out from in front of my truck and get it in the service spot of my driveway I could barely keep the car running. Would barely start. It would start on one cylinder and if I feathered the throttle it would catch on 2 more occasionally.
Another note after constantly cranking and trying to move the car there was obviously a large amount of fuel making its way to the cat because she was smoking hot.
I let it sit overnight and tried to start it the next evening to see if it was a temperature problem and that didn’t help anything. Linked below is a video of what it does now when attempting to start it.
So far I’ve got ordered and on delivery for Tuesday/Wednesday: new ngk plugs, ngk wires, ngk coil, Bosch distributor cap, and Bosch coil.
Valves adjusted within the last 20k along with bottom spark plug tube seals plug wires come out dry, timing belt 60k ago, was cruising at 55mph. Have not had time to check for compression maybe I can tonight but listening to the engine turn over it sounds like it always has with no dead skip.
