I Have Had Numerous Codes Come Up On This Truck. Now It Is Reading That The 4th Cylinder Is Mis-firing. I Now Have Power At Start Off And Thru All 5 Gears, But It Idles Rough

It's been a year and 8 months since the original post - and since his post count is 1, it's likely he will never see this and thus never respond.

I had a similar problem. I have rough idle when my air conditioner is on. Anyway! I pulled into McDonalds and my windows were fogged up/ I had my climate control on top vent. When I changed it from that setting to defrost my RPMs picked up, idle was much smoother. I know I now have a defective switch and need to make sure that when I turn of the air the compressor is disengaging. Weird thing about that was there was not cold air coming out of vents.
