Isn't that the best best thing in the world after all you went through with the frustration and aggravation and when you hear it fire up that since of relief. But as we all know the YJ's purpose in life is to make sure that we are never bored and continues to give us new challenges lol. As soon as we fix on thing one or more surface. I love my YJ.

ya i love when you fix something and it works perfect, but it was short lived. while i was dialing in the choke the idle started bouncing up and down, pulled air cleaner and was watching stepper motor, it was moving in and out. so i think it was trying to recover when i dropped the idle from fast idle maybe o2 sensor is starting to go bad what do you think.

That looks like a carburetor spacer. It is designed to give you more horsepower through higher velocity air flow. This would not cause a miss even if it was leaking. You seal this spacer with gaskets, top and bottom. The miss is caused by your spark plugs being corroded. I say this, because you said you checked all of your wires and did what "dancytron" said. (The easiest way is to let the motor get up to temperature... meaning, hot water is felt through your upper radiator line because the thermostat just opened up. Then turn the engine off and pull one plug wire. Now start up the engine and see. Let it run for a little while. If it is the cylinder causing the miss, one of these "unplug wire tests" should make a major difference, unless you have drivetrain issues in multiple cylinders. In that case, a good vacuum test and a compression test should show it. If it doesn't, I would check electrical again.) Remember, the miss should be easier to detect at idle... the engine is making less noise, so you can hear it better. So after removing a wire and then starting the engine, let it run for a little while. Mainly to let the idle come back down.

Thats cool I have an issue which I thought there was a as well but it's my bottom gasket on my weber. If you get a chance invest in one of these best power improvement especially with 3.07 gears can't wait to see what it's like with 4.10 gears.
