I ran the truck 600 miles towing a car there and back. The check in lite came on my way there. I was running it in overdrive some of the way there on the way back with no overdrive it started popping up thru the air cleaner. when I got home I scanned it, it read miss fire on #3 cylinder and trans temp. so I put plugs wires and cap on it. and cleared the codes. now its missing after it warms up. at a idle just a little for 20 seconds and then really bad. and popping and losing power on the freeway at higher speeds.no check engine lights ether. Please help.
