Yes air fuel ratio out but also timing out low tire pressure ,dragging brakes , weak spark, make sure vacuum advance from distributor is hooked to the port on carb that draws vacuum when given throttle

A lead foot will do it..But seriously sounds like the carb is continuously dumping gas in the motor. Have you noticed it smoking while driving. It almost for sure is in the carburator.

You need to study or research info on tune-ups
Basically it is a sales pitch, as only spark plugs are left

You replacing old spark plugs,gas & air filter etc,that has been
called preventative maintenance for over 20 years
For the last 30 years the vehicles Computer does all the

I have a 1997 chevy silverado with a 350 in it. After going 20 to 30 miles with the air conditioner on it startes to run rough it is getting to much gas if you give it a lot of gas it starts to run ok but...

If it is actually getting too much fuel, the injector or injectors are staying on too long. They are controlled by the ECM so nothing to do with the ignition system.
Another possible cause is a bad fuel pressure regulator. But none of this should be connected to the a/c.
Very strange.
