think this might be a sensor but dont know what one. When im driving down the road sometimes when im giving the truck gas sometimes the engine acts like it is getting no gas then i let up on the gas peddle for a few seconds press down and its fine for a few minutes then the same thing. Ive noticed this happens the most withen the first 1/2 hour i am running the truck any solutions?

use a digital multi meter and backprobe the tps sensor and check the signal voltage with vehicle at closed and w0t and a wide sweep off the full range, should move steady and the voltage should not be bouncing all over the place.
