Need the power of the ORG!.

Ok...my sons truck, 2000 f250, has developed a strange problem.... at idle, or while driving, when you blip the throttle, the rpm's will dip way down and start loping for about 3 or 4 seconds, then smooths out. There was one time last night he blipped the throttle and the rpm's dipped so far down, it died. Starts up fine, runs fine, oil is full, but due for a change tonight. Any ideas?

Fresh. Cleaned out the fuel bowl real good about 2 months ago too. Going to change the oil tonight, check the ICP sensor, and just look into it more. I have heard that after unplugging the ICP and if it runs fine, then thats the culprit...will this send the check ENG light on? And if so, will it go back out when I plug it back in?

Not sure if it will trigger the CEL. But if it does it will go off when plugged back in. Do y'all have a chip on the truck?

I wonder if there is an issue with the pedal assembly like the IVS isn't getting turned on/off when it's supposed to.

I'm thinking maybe TPS or maybe even CPS?

Here is an article on testing. It's for OBS, but the values should be the same for your truck.

97-15A 7.3L DI Turbo
