I'm thinking of tackling this during the week. I'm a little nervous of the two screws that hold the plate on. Has anyone had locktite fail? I'm a little petrafide of one of those pesky things falling out.

I never took the screws out of mine, i just took the tb off, pried the lip off the back of the plate with a screwdriver, and popped 2 rivets in the holes in the plate. Re-installed tb and she been great ever since.

I did this mod a couple weeks ago, I didnt even see this write up on here (I strongly agree if TBI upgrade is a sticky, this should be too) I saw some guy on you tube do it.

My air intake tube was all messed up so it gave me an excuse to buy a volant Intake, i put that on, drove around for a little bit, i felt a little smoother acceleration but at the same time I thought I could be "wanting" to feel smoother acceleration. anyways took her back, pulled the air intake off and pulled the throttle body off. I took the butterfly valve off and shaved the lip off with a dremel and a cutting wheel bit attached. thought it cleaned up real nice, then i took a drill powered wire wheel and a wire brush and some carb cleaner and cleaned the rest of the throttle body up the best I could. put everything together, and took her out on a cruise.......I immediately noticed greatly improved throttle response... I wish I had known this 9yrs ago when I bought her, I would of done it then. Personally I think its a great free upgrade.


Good Write up Vortec Lover. It should be stickied, more people would see it!

Bought my 98 last week, and found this forum over the weekend. Did this mod without removing the throttle body in less then ten minutes. Also did the low budget cold air mod. Definite change in throttle response, and combined the 2 mods made a 2 second difference in my timed 60-90 tests. Not bad at all for the price of a good filter, and 30 minutes. Thanks for the heads up on this.
