Upping idle with idle/set screw

[04lss]

Hi all,

 

My idle when in gear is about 550 as seen by torque through the obd reader. On some of the hotter days i have seen the check gauge light come on for low oil pressure. If i put the truck in neutral and let the RPM climb back to 600-650 the light goes off and the pressure stabilizes a bit higher.

I plan to rebuild an engine for the truck in the spring, but for now id like to bump up the idle to keep pressure at a better level. Can i use the set screw on the throttle bracket to do this? My goal is about 650-700 in gear.

 

I also have HP Tuners and can license the truck and set the idle that way. Id rather not spend the money to license the truck but will if i need to.

Most the TBI have a rivet that needs drilled out to get to the set screw, if yours if open you can use it to adjust idle speed. 

May try relearning the idle control valve as well.

Mine has the wierd center port setup. Not the standard TBI. I can access the screw. I just want to make sure that pushing it up using the screw wont damage anything.

no no, you adjust the idle by bending the tang on the tps

closed i think is .48-.5 volts closed and cold. warmer temps you can adjust it to compensate
