Hey everyone, i'm new to this site and just purchase a '94 2dr Yukon. This thing is an absolute blast to drive and i mainly got it for the winters here in chicago. I've run into a couple issues and have a few questions:
1)I know this is a truck and gas milage shouldn't be a concern of mine, but i woul dlike to know how i can improve the gas milage, i've replaced the plugs and wires, it has a 3 inch exhaust and a short ram air intake with a functional cowl hood.
2)I just found some cheap 22" rims for $300 on craigslist (will be using the stockers during the winter), so i figured...what the heck.... I'm wondering how it would affect the gas milage and transmission if i were to swap 4.10 gears into the front and rear diff.
3)sometimes it will shutter when its idiling, it has 195k miles but i figured after a minor tune up and cleaning the throttle body, that should have cleared up....should i use seafoam??
Thanx in advance for your help!!!
