mine stalls all over the place. from idle up. my fuel pressure seems to be low... will confirm that tomorrow. my reasoning is that if the pressure is low, then the fuel volume must be as well.

otherwise... good luck with it.

manual or auto? i have a Ranchero with a c4 automatic, and it has a bad torque converter. times ill get a wild hair and punch it, the thing will jump then die. so tranny could be choking out the engine.
i also concur on the fuel pressure theory, choke could not be opening fully and its killing the engine when you mash it.
CODES CODES CODES is one thing ive learned. most Orielly/Autozone/Advance will check engine codes for free.

Default Válvula de purga del cartucho de vapor "CANISTER"

hola buenos días señores yo soy nuevo en esta comunidad nesecito "AYUDA" tengo problemas con la marcha minima del carro ya le e echo de todo inyectores bujias cable empacaduras del camarin mangueras de vacio filtros de gasolina (bomba y linea) sensores de oxigeno sensores de temperatura MAF, IAC servicio cuerpo aceleracion valvula pcv todo original motorcraft o ford part y nada la falla se presenta con mas intensidad cada vez que le lleno el tanque full creo que lo que me falta por cambiar es la Válvula de purga del cartucho de vapor (canister) tengo entendido que esta recoge los vapores del tanque y los reinyecta al motor por medio de una manguera de vacio que viene del cuerpo de aceleracion, lo que puedo notar que esta manguera a la altura del tubo de llenado del tanque donde esta la tapa siempre tiene succion el carro falla en minimo y cuando le exijo no avanza agradezco su colaboracion "POR FAVOOORR"
