i have a 1995 toyota pick up that stalls if its in idle or in gear and not moving( If its in motion it drives perfect) when i first start it up i smell faint gas vapors but it goes away. My plugs/rotar/cap, fuel filter and injector are all in good shape. Any ideas? if im driving it hauls nuts, But as soon as you come to a stop it dies. Any help is appreciated. Thanks.
