So I have a problem and I cannot figure it out. I have rev surges. I have cleaned the throttle body, I have cleaned the IACV very well... It still has a high idle and the surge. Cleaning the IACV lowered the surging a bit. I'm changing spark plugs as I'm sure they're bad lol.

 

this mite help you.

 

Thanks I will see if that helps

 

Check for vacuum leaks, too. Although easier said than done, vacuum leaks after the throttle body can cause this to happen

 

My car is a D15B2 and I can't find the Fast idle valve.

 

This is what I cleaned
