My S5 vert needs to have the idle TPS adjusted. But there is one problum......... I dont know how to do it! Please help.

 

s5 tps are auto adjusting.

 

HHMMM. Ok. Then here is another question. When i i have my foot off of the gas the check engine light comes on. I had a friend push the idle TPS further in and then let it out. When he did that the light went off and then back on when he let go of it. Do i need to just replace my idle TPS?
