Engine Stalling

[starscream_r32]

Hey all,

Now having issues with my car stalling.

Every time after taking my foot off the gas pedal my revs drops and my car begins to stall.

Car fights to alive (either that or choking) and most cases it stalls.

I have to give the car some gas to keep it alive and then it's fine until the next time i back off the gas.

Now hear is the thing.. car was fine before i cleaned the AAC and Air Reg.

Yes i have a bov and yes i've got a nistune board.

However i never had an issue until i did the cleaning tutorials.

Any advice guys?

Yes i've checked hoses and AFM has been cleaned.

Could a gasket leak either on throttle body or AAC be the cause?!

Thanks.

What air reg ?isn't the aac an auxiliary air control valve did you adjust the idle after wards and did you put the aac back. Together properly have you checked ecu for codes
