I finally have my truck on the road, however I've got a few problems I can't seem to figure out.

Problem #1: My truck is equipped with a 5 speed manual. Sometimes it'll drive fine, and then all of a sudden it'll start misfiring like crazy, at 60mph-65mph, and it stalls out and I pull over and restart it and it'll drive like nothing happend. Other times when I pull out of first it'll act like like I'm in 4th gear (i.e. bogs down, wants to shut off, miss like crazy) and when I push the clutch in it smooths out and it's fine until I pull out again. Then I shut it off and restart it and everything's normal. Check engine light for the Air Charge Temperature Sensor. Replaced it and it seemed to work for a day or two and now it's doing it again. I can't figure it out. No engine light.

Problem #2: Headlights, and tailights. When I'm driving the headlights randomly cut out and all the other lights are still on. dash, tail, brake, etc. I wiggle the switch and it's fine and then it does it again. Pulled out the switch and found the connector melted and the tan and white wire bubbling and melted. The taillights also keep popping, i've replaced it twice in 3 days. Checked for short. Could not find any, unless it has something to do with the headlight switch and connector.

Any advice, help would be appreciated!
