Hello, my 94 4Runner V6 5spd on the way to work this morning was sputtering the entire 7 mile trip..didnt want to go over 60 miles per hour. (It would if I pushed it, but normally it's not a problem) The car wasnt vibrating too bad, and the oil pressure was just a little over midway (which is higher than usual for mine)...could this sputtering and slight shaking be from not properly warming up this morning, and if so should it have lasted that long? Fuel filter, exhaust problem? Any ideas?

I'm thinking the fuel filter probably?

Spark plug wires,,,spark plugs,,,?

Thanks for any help or advice,
