Stalling out!!!

[cperezsvp]

i have a 1990 bronco ii and it will run idle, but once you start driving it will stall out, usually within 5-10min. what could this be? i had the valve cover gaskets and spark plugs and spark plug wires replaced. I do have some oil on the spark plug, and it sounds like it might be skipping a cylinder. any ideas or common problems?

I know my 90 b2 if you dont let it warm up really good it refuse to go lol I think my idle air control valve is weak

hmm i'll have to look into that. at first i thought maybe a fuel problem but i replaced the pump and filter. I think i have a faulty gasket some where and loosing spark, it back fires then the rpms drop and it dies... embarrassing!!! LOL
