Hey guys, i need a little push in the right direction.

I went up on the full power screw some more and need to drop my idle speed. I just cant seem to get a wrench/socket on the jamb nut, and have a really hard time getting a screwdriver on the screw. Ive tried all of my wrenchs, sockets, extensions, wobble joints, rachets, and 15 different length screwdrivers. I know one of you guys has a trick! I would really like to leave the throttle bracket in place and not remove the boost tube for the AFC.

 

10mm GearWrench or similar (Kobalt's did NOT work due to larger than 5* radius needed to make it click) ratcheting boxend is the only way I've found to *easily* loosen the jam nut...

 

If you haven't already, grab some lube and give it a good shot. Then, looking down at the screw, use a flat head screw driver and hammer to strike the side of the nut to break it loose. Once you have the nut loose, using your right hand manually open your throttle to full throttle (with the truck off) and it will allow access to the front of the screw, using your left index finger and thumb, the screw should hopefully turn for you. Otherwise use a pair of needlenose to turn the screw. Use the flat head and hammer to re-tighten the locknut.

 

You meant to say chisel while wearing safety glasses, didn't you? I know you did.

 

On a non-IC truck there is a bracket plate that is held on by 2 of the bolts in the intake crossover and one bolt down below into the block. Take out the 3 bolts and then you can lay the plate down out of the way which makes it easier to get a 10mm spanner at least sideways on the nut to loosen it. I used a bent paper clip to turn the screw.

and once you get it loose..... take it OUT.

Take a flat piece of bar approx 1"x5 1/2" 3/8" thick. Drill holes about 3 1/2 inches apart. Tap one end for a bolt. Thread nut onto bolt then put bolt in threaded hole. Attach other end to the drivers side pump bolt mount. Pivot it up so you can use the bolt in the threaded hole as a stop for your throttle linkage.

Takes about two minutes from here on out to adjust the idle.


(rampower's idea... not mine)

 

I like Cootz's method - just struggle with it until you figure something out.

 

I did the bend a cheap 10mm gig. Then use a knuckle buster across the flat of the 10mm handle to turn the jamb nut. I borrowed the idea from this board, the resource of resources for first gens!

 

My mind's eye is having trouble visualizing this. Can you splain more - or better yet for us cognatively challenged - pictures!

 

Ask and ye shall recieve.

 

*That's* cheating!

(Mine will be done that way by next week! )

 

Yes. I agree! You need to take that off and bust your knuckles like the rest of us.

I wouldn't adjust the idle on a VE with the factory adjustment again if I had to. This only takes a few minutes to build and install, and it makes adjustments a snap.

 

Yuppers!!!


I owned the truck less than 24 hours.

The idle was fixed. (using that method)
The bracket was cut (the one that gets in the way for removing the shutdown solenoid)
The wires were clipped to solenoid and replaced with ring terminals.
3200 Gov spring installed


I think I like the idle adjustment best.
