It’s not holding idle to throttle correctly so the transition from stepper to throttle isn’t right

So NZ, can you give me a quick instruction on where the stepper motor is and how to clean it good? I assume its on the throttle body but not sure where or how to get it out. Does gas tank need to come off? I have looked around and tried to find the info but keep running into dead ends. And well...………………………………….I'm lazy. thanks, rj

take seats off, remove the 4 stainless screws holding plastics on and the 1 tank bolt remove tank n wire hoses (5 min job)
Directly below you will see the throttle body take it out remove black stepper motor clean clean clean the passage with Q tip brake clean etc and gently scrub the styepper nose. check throttle plate closes off correctly reassemble and reset ECU.

Thanks NZ, you the man, really enjoying the 300 kit I got from you. It's added that little oomph where it was needed power wise, rj
