No CE light will activate.
However for proper operation of the rest of the systems, you should have a custom chip made to completely disable the AIR settings as they do affect the 02 sensor when active. Its an offset
later

Re: smog equipment delete, will this cause engine light
kevin we keep on doing this little dance, illegal versus street legal. lets just agree to dissagree.
yes, its illegal to tamper with emissions stuff yadda yadda
but
yes, it gets in the way. yes you can remove all that stuff and still pass smog, yes, itll clean up the engine bay.
but the decision is up to you.
and no it wont set off a CEL

The EGR doesn't use engine vacuum, it source is throttle body ported vacuum nothing else should be using that port's vacuum.

Re: smog equipment delete, will this cause engine light
Keep the stuff on your car. Eventually Obama is going to make every state do emissions testing as he tries to create a happy green USA for us all to live in. If you dont have the parts its going to cost you a LOT of money to buy them again.
Also, in the meantime, every time you remove your emissions devices, you are telling the smog-***** that the current laws are not tough enough to stop you, so now they have to write tougher laws that affect the rest of us. Thanks a lot!
We here in SoCal have proven that you can have a fast TPI car and still pass the emissions test. You dont have to remove anything because its not going to give you much gain, if anything at all. I removed my a/c and I can access both sides of my engine very easily, even with the AIR lines.

Re: smog equipment delete, will this cause engine light
Kevin91Z is right. Emissions testing is not going away, eventually it will be in your county no matter where you live. I'm proud that my 20 year old car runs cleaner and gets better mileage than a brand new pickup.

Re: smog equipment delete, will this cause engine light
I removed my smog pump this weekend as it froze up on me. I left the metal tubing that goes into the manifolds but capped them (x3) with 1/2 iron pipe caps.
My check engine light came on.
Any suggestions?
Do you have to do anything with the two plugs that were unplugged?

Re: smog equipment delete, will this cause engine light
Good advice. The speed-density system from '91 should not be looking for the electrical load (35-50Ω) from the port or divert solenoids as a later ECM/PCM would. Don't be surprised if the O² sensor is reporting lean, potentially from a leak in the caps you installed on the air injection fittings. The threads are not NPT, so a standard pipe cap may not seal very well.

Re: smog equipment delete, will this cause engine light
I try to tell people that and they just ignore me. The threads are 1/2"-20. People refer to the fittings as 5/16" inverted flare. Well the flare may be 5/16", but the threads are 1/2"-20 which is a bolt thread, NOT a pipe thread...

Or these (and that's not rust. It's copper-colored anti-seize)...
