Emissions Stuff?
I'm still completely new to the TPI type motors and i have absolutely no clue what this thing is and i'd like to know what it takes to delete it? 


FYI i have not done anything to this car yet, i bought it after it's been sitting in a garage for almost 9 years.
Links and an explanation would be highly appreciated.

Re: Emissions Stuff?
That is your air pump diverterr valve. You should have your memcal reprogramed if you remove it. You will also need a shorter belt when you remove the air pump and will need to plug the air tubes in the exhaust manifolds.

Now will this effect me negatively, positively or not at all?

Re: Emissions Stuff?
If you have a visual SMOG inspection than it will not pass without it.
Also =
Diverter/bypass valve controls air flow through the exhaust system during a cold start to help reduce emissions
When removed, vehicle may experience rich exhaust during engine warm up, catalytic converter damage, premature oxygen sensor failure and/or excessive hydrocarbons in the oil causing internal engine damage.

Re: Emissions Stuff?
Washing all that filth off your motor will have more effect than deleting THAT, just from the weight reduction.
