2.5 question

[pug]

I have a 1990 2.5. It starts and idels good. When i get on the highway it starts cutting out but still idels good. Any ideas thanks

O2 sensor, fuel pressure, fuel filter, would all be things to look at. Mine would cut out at times while driving too, but never at idle, turned out to be the O2 sensor, cleared it right up, but change the fuel filter too. I had a Ford F250 once that would cut out like that, it turned out to be a gas tank full of rust that would clog up the inlet screen, and pack the filter full of crud...not as likely here, but still a possibility.

I will try o2. How do you check fuel pressure.

mine had the same problem.. it would go fine in town but get on the highway and it would choke puke and bog out till i got off the gas... turned out to be the fool pump

Does it feel like the truck completely loses power? Like you have your foot on the gas but nothing happens (while its happening)?

I'm having that type of issue and replaced the plugs,wires,fuel filter, cap, rotor with no luck.
