sticking throttle body

Asked by Jul 27, 2017 at 03:25 PM about the 2016 Kia Sportage SX Luxury AWD

Question type: General

Kia Sportage 2016 - Sudden, involuntary acceleration

1 Answer

920

Is the manual movement of the butterfly smooth? Possibly chewed up drive motor gears? Clean out throttle body with carburetor cleaner and wipe out all black crud. Also clean MAF sensor (between air box and throttle body). YouTube videos can assist in this. Do not touch internals of MAF sensor. They make a special spray cleaner that will sufficiently clean these. I have seen online mechanics use cleaner soaked q-tips to gently clean internals of this sensor.
