I just bought a 1989 k5 w/ 350 tbi 700r4 The problem is when I start the truck it runs great, then as it warms up into it's operating range it starts to stutter and chug like it's choking on gas. (I can smell the gas) It does this until the stat opens an then it smooths out and works good. Is this a computer problem? My temp gauge was acting funny so I took a look at it and found that the wire was green all the way through. So I cut that part out and now the gauge works but the chugging persists. Any leads you can give me are appreciated. thanks.
