I'd like to see one of you intercooled guys put up a dyno sheet with 300+ with stock injectors :lol: . Mine bottomed out in the threads with no run away. I had to re index the throttle shaft to make it idel.

13mm wrench for the jam nut and a screwdriver. Maybe a Dremel depending on how far you want to take it :wink:

Do you have gauges? That would determine how far you should go with it for now.

nope no gauges dad had to have a new truck so......what does it do for power/smoke. I kinda want to know what the deal will be cuz they don't look to kindly towards my smoke at school.

so 13mm to take the nut off then a flat head screwdriver cw a turn to be safe. Think it will run away? what makes it runaway?

You don't need to take the nut off, just loosen it up. On my early 91 I only got 1/2 to 3/4 of a turn before the collar bottomed out. I went back after I got gauges, cut the collar off, and turned it up more. I doubt it will runaway with just 1 turn, but do the throttle check anyway. After you have the screw where you want it, blip the throttle. If it is slow to come back down, back it off. If not, you're good to go.

okay thanks. I just wondered what to do exactly since those directions are a little bit fuzzy bout that. What exactly will the one turn do? and should the engine be running when I do it?

It is sort of harder to get to than anybody implies, isn't it? :lol:

I pulled the whole screw out. Then after getting the collar off (and messing up quite a few threads :oops: ) I turned the locknut a few times towards the end with the hex on it. Then I took a eyeglass screw driver and turned it until I couldn't turn it no more. Need to add some metal to the end of the side that pushes the lever, I ran out of threads :twisted:

how do you get anything in there to do anything with it? I can't get a screwdriver a socket a wrench nothing. absolutely nothing. I want some smoke but if this is this hard then screw it.

hmm, once u got it out, n the threads fixed, it is a simple reach with a 6mm socket on a small 1/4 drive ratchet.

Once I got the idle screw out, it was reversed as per GL's advice and is now easy to work on from the front with a short screwdriver

Yup, pull the fuel return line, tie it out of the way, and use a 6mm and 1/4 ratchet. Thats what I do, yup, yup, yup!
