Have a even higher idle now after cleaning the TB. Probably cleaned it wrong or something 😕.


Video that it works other than my high idle

You assumed correctly, you fucked up the coating sealing the throttle body plate to the Throttle Body. Don't use agressive cleaners or scrub the throttle plate...
