Mechanic Help!!!

Did you try the ole starting fluid or whatever spray in various spots and see if the idle fluctuates.... helps you find your leak. That's what I always do to find leaks.

This would be very wise to do as well!! wd40 works also.

I would double check the throttle cable, sounds like it's kinked or hung up some how.

This or the TPS is nit bolted right

[IAFFHunter18]

Ok. Cables are good. Both have slack when let off. Checked the TPS position its good. This thing has me stumped!!!!!! I have asked several mechanic buddies and no one can figure this out. I dont get it.....

[miket]

Did you do any kind of TPS relearn? Looks like procedured vary based on year. ( cable vs wire etc )

[miket]

Looks like may need to do tps relearn

No sir, I have not tried this one but will. I greatly appreciate any and all the help all of you have provided so far. This one has stumped several of us.

Make sure to ck the ground wires at tstat housing. Recommend cutting and installing new eyelet terminal to this. When you pulled the intake did you remove the injectors out of their respective ports?

[IAFFHunter18]

No sir, didnt mess with the injectors at all. Left them in place.. Checked the ground there and the 2 on the back on the motor and all are hooked up.

Doesn’t that truck have a spider injection setup? I didn’t think you could remove the individual injectors on that.

Yes sir, has the “spider” injectors. I did not remove these just the housing and replaced the gaskets with new ones.

Anyone else with some ideas??? I have hit a wall mentally on this one.
