Hey everybody, hows it going? About a week ago after I would start my truck it would idle for about a min then the rpm's would just keep decreasing till the truck died. If you hold down the gas pedal with your foot the truck will keep running, but without controlling the rpm's yourself the truck dies. Even when the truck gets to operating temp it still dies. After it started happening I was looking at the engine and decided to see if a tune up would help so I replaced the spark plugs, wires, distributor cap, and rotor. But it didn't help. Any ideas would be greatly appreciated. thanks.

 

One thing you left out of the tune up was a fuel filter.
The thing you left out of your post was truck details.
