I might have to go pick up a few cans!

Look carefully they have 2 different temp ratings. I always get the 3000 * paint it last longer

 

[O'Rattlecan]

That's good taste, Cliff. I painted my upper intake plenum the same color years ago.

Thanks Ryan, any idea on the high idle?

 

[O'Rattlecan]

I remember somebody saying something about the idle set screw. You didn't fiddle with that, did you?

Ryan

Is that on the TPS?

 

[O'Rattlecan]

It's on the mounting plate on top of the throttle body by the cables.

Ryan

No my son just bolted the mounting plate on but didn't adjust any screws or cables.

 

[O'Rattlecan]

Is the throttle sticking or something? It won't go lower even if you wiggle the throttle around and try to make it go as low as it can go?

Ryan

 

[Ridgerunner]

I haven't tried. I thought it was set permanently from the factory

Check your IAC to see it its working. Unplug it and the engine should stumble.

 

[O'Rattlecan]

It can be adjusted. I don't know the history of the truck, perhaps the previous owner adjusted it to keep it from dying to compensate for an idle problem rather than fix it. Or the cable could just be sticking open further than normal.

If that isn't the problem, I don't know what to do, you're getting too much air in the engine, and that will mean the truck delivers too much fuel.

Be Right back I will check it.

I will look tomorrow and see how to reset the idle screw.

 

[Ridgerunner]

Randy I started my truck and unplugged the IAC it ran smoothly,the idel dropped a little plugged it back up while it was running and the idle went up. I cleaned the IAC 2 days with carb cleaner.

 

[smokey]

Unhook the throttle cable it may be binding. if that isn't the problem you have a vacuum leak some where

 

[Ridgerunner]

Thanks I will check it tomorrow and see what I can come up with.

 

[Ridgerunner]

If the IAC is plugged and the engine stumbles does that mean it's bad?

 

[O'Rattlecan]

No, it should stumble without it.

Randy was going down the right road, if it's not the throttle and the IAC checks out fine, you might be looking at a vacuum leak. That's very likely since you just took it all apart and put it back together.

I did unplug it and nothing changed

Bssic troubleshooting is all this needs. Been down this road many times over the years.
