Just finished going through my new to me 2011. My only complaint about how it runs is just off idle. Only noticeable in low or reverse, especially if the engine is cold. Backing out of the garage or putsing around the yard. It seams to hesitate or slightly stumble just off idle. It idles perfect and has smooth power once you get going. Has a small pop or minor backfire once in a while. Like a sputter. Maybe a lean or rich problem? Just changed plugs, cleaned intake and tmap, fresh fuel with treatment. Definitely runs better, but not perfect off idle. Checked for exhaust leak but don’t see any. Suggestions please. Hope it’s not TPS. I am not good with electrical. Not great with mechanical either.ha ha, but I’m learning.
