2000 3.0 Strange Problem
OK...When I leave in the morning and the ambient temperature is cool the truck runs fine. When I leave work and the temperature is warm to hot the truck backfires through intake, pings bad, has a miss and a surge and no power. There is no CE light, this is about to drive me nuts. I was just hoping (doubting) but hoping someone else might have had this problem so I don't just have to start replacing things until it's fixed.

Before replacing anything, why not visit your local parts store and see if there are any codes stored? The symptoms are of an engine being run too lean. Check the MAF, and the ribbed airway from the MAF to the throttle body. They can have hidden cracks and allow air the MAF & computer don't have a clue about. That can also affect idle speed.
Other things are fuel pump & pressure, regulator, filter and the ECT and ACT sensors if you have them both. ECT is coolant, ACT is incoming air temperature sensors. The computer leans out the mix when they read 'warm/hot', which fits.
