choking and dying when starting
I have an 86 chevy s10 pick-up 4x4 extended cab V6 2.8L. First start of the day, she fires up with no problem. After I drive her, turn her off and restart her, she often chokes. She will chug and die numerous times and smells horribly of exhaust/gasoline. If I step on the gas to prevent it from stalling, the gas will just cut out, even if I am still pressing on the peddle. It doesn't do this every time, but it is pretty close. And it only happens after the vehicle has been running. Also after it gets started once it goes through the choking and dying, it idols extremely high. I can go a steady 20mph without putting my foot on the gas. She is only getting about 12 mpgallon. I have tried to change the fuel filter but cant seem to get it lose, it is clamped on too tight. Any thoughts?
