Did you ever figure it out? I'm going to put something in my 2004 Sierra. I like Compustar a lot, but the Viper install they did on the Grand Prix looks very easy the way they did it. https://www.the12volt.com/installbay/forum_posts.asp?tid=20338

Hello friends. Another one for you. My 1990 cutlass 3.1. Has a rough idle when it warms up. Replaced a lot of items and even a charcoal canister. Thinking the evap is bad. Which it was anyway. But the car starts acting up when it’s in gear and idling with foot on brake. Which I also noticed as my foot is on brake the engine kinda surges and I see my volt gage dip up and down a little. But enough to make the engine not perform as it should. I have to mention that I have a power master 3 brake system. Not a fan. Any ideas would be appreciated.

do i leave it white ,or do i use, the red line ?

Rear head access is the part that makes a simple intake job turn into a whole project. At least the teardown should settle whether the intake gasket was the real culprit.

That extra 2mm really wakes these cars up in the corners. Nice when a parts hunt ends with an actual upgrade instead of just getting back to square one.

You are 100% correct, I found a mechanic working at a local chevy dealership who has over 50 years experience. This source will not last forever, that's for sure. Per hour rate is not cheap but that's the way it goes.

Lol the classic garage vanishing act, the stuff you put away carefully is always the hardest to find. Bet they turn up the day after you cave and order a new set.

A whole summer of cold air out of a 3.4 car feels like a small miracle tbh, and a mechanic who actually wants to touch that motor is worth hanging on to.

And I still haven't found those door speakers. I will. Someday.

Was a great summer, the A/C performed as it should. Successful repairs is always a good thing, it's why we keep on driving these cars, or at least one reason, anyway.
