    Slight hesitation on acceleration

    Upon first applying throttle from a stop the engine hesitates (rpms drop about 200, from 800 to 600) then the car acts like normal under the rest of acceleration. I have no trouble codes and it's not a misfire. Brand new air filter no obstructions of air flow going into the engine. Spark plugs have 15k miles on them. MAP sensor reading seem to be normal. Any suggestions where to look for the problem? Cant seem to wrap my brain around this one...

    Like clean it or clear its adaptive learn? And if so how do you clear it? I can clean it as I work at an automotive repair facility but have never had to clear a throttle body.

    Do you have a scanner that will read live pids?
    I would watch the tps while rolling thru the movement (key on engine off) then if all looks good. Then record tps and afr while driving. See ifs it’s lean or way to much fuel enrichment.

    Pulled fuse 11 yesterday for about 45 minutes. Haven't had the issue since.

    I was going to toss out the idea of recalibrating the gas peddle. But if the fuse fixed it that's awesome!

    I think it had something to do with the fact that it's been snowing a lot up here in minnesota and every time you hit the gas traction control comes on. I think it must have learned to cut throttle on initial acceleration due to traction control coming on so frequently.
