My truck warms up twice every morning. Idle gradually increases until 1/4 of temp gauge then drops down like it's ready to go...but it's not. If you wait a couple minutes it does the same thing again and then the idle drops at 1/2 temp gauge...where it should have in the first place. Runs fine after that. I don't want to wait a half hour every day for my truck to warm up though. Gas mileage is bad enough as is. Any tips for adjusting the fast idle?...If that's the problem....83 carb p/u
