misfire p302 #2 cylinder
OK this is what it has been doing. You start the car cold, and it runs very badly, just like it would if one cylinder was not firing at all. Then you drag the beast down the highway about 2 miles and while you are sitting at the light it will clear up and run smoothly. At that point it is usually gone.
However every once in a while, it will come back an hour later or so. It will just pop up while you are driving down the road. So I replaced the plug to cylinder #2, and the wires. Problem is still there.
I did a splitport motor swap about 10K ago, and haven't had any problems until now. I am also wondering though if there may be a fuel pressure problem and if that could cause it. I was going to replace the coil, but I thought there would be two cylinders misfiring if the coil was bad.
