May 4, 201510 yr recently have been experiencing a stutter/hesitation at low speed accel. Quit on me twice one day but restarted and I made it home. Car didn't run the next morning. Starts fine, idles at 1500 for half a second then bogs down and stalls. No codes. Also before the stutter issue, I replaced the air filter with a Subaru OEM filter I got from the dealer. It was an oil-saturated type, I've always run dry filters before. I suspected oil had fouled the MAF sensor, cleaning it didn't help so I ordered a new one. With the new one in, I still have yet same issue. I would suspect a coil or vacuum leak, but it runs fine with the MAF sensor unplugged (stalls under load). Has anyone had issues with aftermarket sensors? EDIT: disregard this question: Make sure you connect the tube to the IAC... Whatever default it went in to after the MAF was unplugged stumped me for a second Edited May 4, 201510 yr by pginter96
