What is this?

I just bought a 1991 Z28, and I just noticed I do not have the black box on the passenger side by the AC condenser and compressor. Could anyone tell me what it is? Thanks.

Thats the air pump diverter valve. Part of the emission system.

Yep.
Probably missing the air pump itself too.

Re: What is this?

Sometimes there is a slight clatter from my box, is that normal?

Could a problem with the AIR system cause a lope?? Especially at idle....not too bad, but definately there.

Re: What is this?

Ok, im not familiar with the TPI, i have a TBI, but if it is a valve, than the clattering could be from the valve opening and closing/switching back and forth. like i said im not familiar with the TPI but it is an idea.
