Have your emissions systems checked, it sounds like the computer is trying to kick up the idle so the engine won't die at low RPM because of either an emissions system failure or even just several cylinders performing poorly. A full shop diagnostic might save you hundreds later, because a problem like this almost always leads to failed parts, or even a blown motor, later.

I replaced the malfunctioning “thermal actuator” with the “Warn” Vacuum actuator setup, it’s been working great for about 7 years now, simple install, if I remember correctly, it was about $150.
That’s what engages the front diff into 4wd.

SOURCE: Chevy truck running rough 150,000 miles

Find out why the engine light is coming on, it is the info u probably need to fix the running rough problem. Most auto parts stores will read the codes stored in your trucks computer for free, write them down, and ask what they mean and how to correct the problem. If u need more info, return to this site w/ codes for further help.

fuse f2 , FUSE BLOCK is blower 30amp goes to blower relay
relay is energized key on. Position
relay goes to blower Plus
blower minus, to control , on high control ground fan to ground G202
F2 is in the fuse block, (CAB)
fuse 2, is in PDC and if b low engine dies and blower. too. and vast.
fuse block means CAB box. fuse same place as flasher and CB1/2
blower relay is a the Steering support bracket (quote SM)
end blower, start, answer 2 (idle controls
NO engine told so talking EFI here is not easy. lacking key fact1.
hot engine (it hot 180f to200?) normal it must be.
hot engine 1500 is total loss of EFI idle controls.
IS CEL glowing, check engine light?
500 in drive hot 180f+ engine is same answer. lost controls of idle.
