2002 Chevy S-10 6 cyl Two Wheel Drive Manual 150+ miles

The rpm's on my 2002 Chevy s-10 5speed are all over while driving normally and the truck feels jerky. I have replaced the cam sensor, crank sensor and the distributor...all of these repairs have worked for about 20 minutes or so.... Then, right back where I started! Any ideas what might cause this problem?

It sounds like a throttle position sensor or an idle air control valve. Has the check engine light come on?
