I drove my truck into work yesterday with no problem. Get in to drive it home and it doesn't want to idle at first, (keeps shutting down) then, when I get it to run, the idle speed is going up & down.

I've been running on the same tank of gas since last Friday and I still have 1/2 a tank. Thinking I might have bad gas, I dumped a bottle of fuel system drier into that tank and switched to the rear tank for the ride home. It didn't want to take much throttle, so acceleration was poor (stumbling like its too rich). I finally got it up to highway speed and it improved enough that I switched back to the front tank for the last 2-3 miles and didn't see a difference. Without a load (neutral) I can rev the engine with only a minor hiccup just off idle.

This morning when I started it- pretty much the same. I doesn't want to take anything past a very light throttle application.

Throttle Position Sensor? Partially clogged injector? Ignition module or coil?

Does anyone have any insight or experience with this? Please advise.

Thank You! -MidSouth Mitch
