after buying a 93 ty with 30k on it I found it had an intermitent stutter. After replacing plugs and wires (twice) distributer cap, rotor, ICM, ignition coil .... all to no avail (other than it needed it anyway) I finally decided to check the fuel pressure, results showed that the FP was jumpping around even at idle, so i ordered a walbro 255. I just finished putting it in (that was a fun job :roll: ) this thing pulls like a raped ape :tup: :tup:
