Hi Scotty.

Been a fan of you for a long time .been watching your videos for long long long  time thank you so much.

You had helped me fix my cars through out the years with your videos .

It is my first time sending a question

I have a 2019 Chevy Cruze ls 

49k miles 

Check engine light came on with codes 

P1101 intake air flow system performance 

And secondary DTCS 

P0101 MASS air flow sensor 

- besides de codes 

There is a hissing sound while pressing on gas after going on highway speed 50-60 miles 

 This morning I started by replacing the 

Intake air filter which it was very dirty lots of debris inside 

Cleaned the throttle body 

This may have helped to remove the codes at the moment have been driving car for 10 miles will keep driving if codes come back 

But hissing sound it's still there while car is running and pressing on gas when going highways speed 50-60 miles 

Thank you so much for your help

Much love Scotty
