when i rev her around 4000 rpm i get a sputter like its missin. i put tr55 plugs in it acell 9000 wires.
it used to be real bad, till i changed the plugwires. it still isnt totaly fixed. my gas mileage is 13.5mpg. it kinda stumbles very slightly when it idles (not hearable but u can feel it wile sitting in the car)

i was thinking it might be a bad injector, what do you think?
i wanted to get injectors in the future when i do my cam and headers, so gettin em now wouldnt matter.

gas mileage isnt a problem its the damn sputter. ill just hope mrs opti dont give up the ghost.
