    he-he-he-he-hesitation

    Poked around quite a few threads on here and NASIOC, thought I would make it official. My 02 sedan with 150K suddenly started to stutter and hesitate. I was driving with cruise on the highway ~70mph, went up a hill and the engine started sputtering to keep speed. Took it off cruise and got back into city driving. Seems to go through 1st ok, 2nd and third really hesitate and shudder on acceleration. It seems like the hesitation is mostly low-RPM, once i get higher or into boost it seems to smooth out a bit, but it's still shakey. I have a carchip which I pulled the CELs last night - P0032 and P0136.

    Most conventional wisdom on here seems to suggest replacing the from o2/AF sensor. Where should I go (online) to get one? Couldn't find on subaruparts.com
