your exhaust is probly stopped up
have you checked the oil level in the transmission ? I'm betting the answer is no
it could have a bad air filter or the fuel is clogged some where. or the batt could be going bad.
Its broke - get a new car
carburettar needs adjusting
Hand brake? I thought the last GMC with a hand brake was in 68, but I could be wrong.
Your car is not getting enough fuel if it hesitates to take off and shakes. The fuel filter might be plugged or you might have the wrong gas in your tank.
Your fuel filter could be clogged up or you could need a new fuel pump.
It could be the mass air flow sensor located on top of the breather tube by the air filter. One way to check if it makes a difference is to disconnect it. Drive it and see if it still hesitates. If it does that could be the problem, was on mine. It can mean alot of things really! Timings off, fuel pressure regulator is set too high, plug wires are frayed, O2 sensor could be wired wrong, or going bad. Check all of these!!
It could be the firing order is wrong
