Question about 1998 Chevrolet S-10 Pickup
You can't change it, it is controlled by the ECM via the Idle Air Control valve. Its a small solenoid type part that is screwed into the throttle body about mid way. It opens/closes by command to allow more or less air into the system to raise and lower the idle. If its stuck open, you will idle too high, closed is too low. I have replaced a lot of these over the years, carbon builds on them, they get hot/cold a lot, and they do fail. If you need to replace it, you likely will just install it, plug it up, then drive at 35mph or more for a few minutes to allow it to calibrate itself. Good Luck !

Have you had the truck scanned for codes? If so, what was the code, codes? Why did you replaced those listed parts. Can you hear any hissing noise coming from the engine or engine compartment?

Normal thing that happens as long as onone (worked) on it, is the vacume hose going to the engage sevevo under the battery box has fell of on either end or is brocken on the way there. Then the once or now leaky battery acid ate up this same servo. then the cable going to the front axel breaks sticks falls off or even someone needing one climbed under your truck while parked somewhere to get one to replace their brokeen one now you don't have one then theaxel engage arm or gearset is damaged

Please don't forget to rate!!!!
2.2L Engine When installing new lifters, a pre-lube should always be applied to the lifter body. It is also a good idea to prime hydraulic lifters by submerging them in clean engine oil and depressing the plunger using an old pushrod. This allows the internal components of the hydraulic lifter to coat with oil before initial operation in the engine. All lifters should be replaced when a new camshaft is installed.
If any valve train components (lifters, pushrods, rocker arms) are to be reused, they must be tagged or arranged during removal to assure installation in their original locations.
Remove the bolts retaining the lifter anti-rotation brackets ...
... then remove the anti-rotation brackets
The lifters are located in bores in the engine block
Use a lifter removal tool to remove the lifters from the bore
If installing a new lifter, coat the lifter body with a suitable camshaft pre-lube
