Re: Adjusting Idle Mixture Screws Does Nothin - Quadrajet

Thank you all for your advice, I drove the truck in to work today for the first time, and after I drove it back home (10 miles) it was finally warm enough to where after screwing each side in one at a time the truck finally responded and the motor died

Then I turned each screw 2 full turns out from bottoming out and learned that its around 2 full turns that the RPMs are at their highest turning the screw out any further yields no better results, as you also suggested

I tried turning the screws in a bit after that to find that sweet spot but I think the best results were at 2 full turns out

so thank you all for your help, I consider this job done
