I am new here, so i suppose i should introcduce my self. Im Steven, im 24 and live in Indiana. I just bought an 87 chevy R10 and it came with a few lingering issues that the previous owner didnt care to fix. I hope that someone here has the smarts to help me out. First of all, the gas pedal is at first VERY hard to push. Then out of no where, it pushes in and accels rapidly causing me to spin my tires occasionally. This also makes it very hard to keep the truck at 30-45 mph. Secondly the truck barely blows heat into the cab and wont defrost at all. I have been told that this could be the vacuum home? In the engine compartment on the passenger the this a hole sucking air in that looks like it needs a hose. The only problem is, I don't know where the other end of the hose should go.
