That's not a stupid question, most people don't know about that, and I think it is computer carb. Is this right guys?

Re: question on a 1986 GMC 1500
My 86 GMC K1500 had the computer and the "electronic" q-jet carb setup. It caused me a lot of grief. I finally gave up and sold it and bought an 84 Chev. My carb worked fine, but the truck refused to allow spark to the ignition circuit unless it wanted to. When it ran, it ran great.
That minor rant aside, your computer is up underneath the glove compartment. You'll see it up there...
