Emissions Equiptment

[thuber3040]

What emissions parts come on a 1990 gmc 2500(guessng light duty) 2wd with a 5.7?

 

My engine was redone in a non smog area and I will need to smog it soon. I dont want to waste my time if all the stuff is gone..

 

Thanks to all

It is twenty years old, smog exempt in some places.

But this is what it probably came stock with:

Catalytic Converter

EGR

PCV

Evaporative Emissions (gas filler cap and neck area)

Air Injection system

O2 sensor

 

 

I am assuming that your truck still has the stock ECM that came with it. If your check engine light is not on, then you are probably ok.
