Did a LIM/UIM and 20 miles later have a Cylinder 4 Misfire
Just got the car back together and running last night after doing a lower intake manifold gasket on my 2000 SSEi. Everything was doing good last night for my test drive and even on my drive to work. Leaving work, SES light came on, and it felt like the car was surging, but still running ok. Put it on a scanner, and it came up as a cylinder #4 misfire. Got home and pulled the spark plug and it looked ok. I even swapped the plug with one from the front #3 or #5. Still doing it, got a different wire and tried it on cylinder #3, #4, #5 and still doing it. Almost feels like it'* not surging upon initial start up, but starts a couple seconds later, I had pulled the wire off the coil while it was running, and it'* sparking. I'm not sure where to go now and don't want to take it to a shop.
Looked back in the owner'* manual and a previous owner had replaced the spark plugs and wires about 2 years ago, less than 30000 miles ago.
Anyone have any ideas?
