Can anyone help? Its a 85 w150 ram 4x4. Truck is running very ruff, doesn't keep an idle if I don't stay on the gas it will die. While driving it feels like its not getting enough gas spills out lots of fumes in fact the hood is black from it. I thought it was the vapor canister so I removed it does the same thing. I was thinking of replacing the goose neck on the smog pump this weekend to see if that changes anything. I have a new vapor filter but can't find where it goes so I can replace it. I do need a new exhaust system pipe is broken going into the muffler between Cat. I can't step on the gas hard either the truck will also die have to just give it enough. Funny thing made it from Florida to Tennessee pulling a uhaul trailer 10hrs no problem ran great.
