Got a 02 sport 5.9 and I have replaced cap rotor, plugs and wires, TBS, and checked the fuel presser which was good. After doing all this it still runs like crap. starts up fine and idles fine. when driving it sputters allot. Hooked it up to a computer and everything was fine... even both O2 sensors. ??? What next ??

OK!! so it wasnt the fuel injector ... although i did have one that was bad... fixing it didnt help.... its almost worse .... wont tack over 2000 now. when I had it on a computer the O2 sensors read fine... I did the sea smoke thing and no smoke came out at all .... And from why this hole thing started from in the firs place replacing the plenum doesnt seem likely ..... next i guess is the cat..
