How to clean a throttle body and Idle air control valve (iac). This shows you how to fix a high idle, low idle, and or rough idle. Most modern cars have an idler air control valve (IAC) that can get gummed-up and you have to clean it.
Be aware that unplugging the IAC can trigger a check engine light (use a scanner or disconnect the battery to get rid of the light). If you have any questions feel free to ask below. If this helps also let me know (I like to know when I help someone out!).
Codes that can be triggered are, P0401, P0505, and P0507

    Since you referred viewers here from your newer video… I'll be giving this a shot in the $500 Mustang. Because what was $100 at a mechanic 10 years ago is $105 for just the part now, without the gasket, and I would like the slow down on quadrupling the amount of money I have in this car. 😅
