I had the P0101, P0171, P0174 errors come up today. I cleaned my mass air flow sensor hoping that would do the trick. However while I was taking a look around my engine I noticed I was missing a nut. Anyone know what size I need? Do you guys think once I get that cover on it will stop my problems?

 

The part is called "Air intake adapter nut". Available at any GM dealer, under $3. Or you can try a boneyard. Clear the codes and drive it, if it doesn't fix the problem, let us know.

 

Thanks for the info. I'll hit up my local dealership tomorrow morning on my way to work.

 

Everything has been working perfect since I got the part. Thanks for the info.

 

Cool, thanks for posting back
