halp

96 maxima.


it started having a bad sputtering problem where sometimes at idle the rpms would blip down 200 rpm then jump right back up but its alot worse coming off the line.

i cant give it more than 1/2 throttle without it struggling to accelerate. i have noticed its really bad when its been at operating temps for a mile or so, sometimes it wants to stall.

i changed the plugs, the fuel filter, cleaned the maf twice, checked all the coilpacks, theyre hanshins so from what ive read that means the stock ones were replaced.

its only throwing 1 code, ks.

i was thinking its possibly a bad o2 sensor because it happens the most when the car is fully warm, but it hasnt thrown a code for it yet.

ive checked/listened for vacuum leaks, saw nothing.

sprayed carb cleaber around the intake manifold gasket, idle stayed the same.

im really lost.


someone helpppppp thanks.


EDIT: also cleaned the tb, no luck.
