Removing all possible emission controls

[TwinFast]

I just realized that I missed one picture, so I will post it here in case anyone in the future is looking at this thread for similar advice.
This is the fast idle test button, I believe.

Thanks for all these informations. You talk about the fast idle test button. I always have eletric issues with this device. Is it possible to remove it and how to proceed ?

Yes, you can remove it, but make sure you run 12v (switched with ignition) to the fast idle solenoid coming out the side of your carb, if applicable. I have since switched to a 32/36 DGEV and don't have that anymore, but my factory 32/32 ADF did.

I'm not well versed in removing sections of the harness, as I ultimately removed everything and designed my own harnessite for the car that eliminated those circuits entirely.

Has any one done any smog removal on a FI car? Wouldn't to do so screw up the Engine Control system>

[Jon124]

The only emissions equipment to remove on a fuel injected spider is the catalytic converter. Many people do this (including me) and there are no negative effects on the engine control module. Depending where you live it may be illegal though.

Do NOT remove the charcoal canister on an FI car. It provides make-up air to the gas tank, and actually does some environmental good with no performance costs.

Can you elaborate a little more on this requirement?

I have my charcoal canister disconnected right now because I had a problem where some of the charcoal granules were sucked back into the carb bowl & clogged things up. I'm not really sure how this happened as I triple-checked that the hoses were routed properly but I'm obviously concerned about it happening again (actually caused the car to stall a few times until I took stuff apart & cleaned everything out). I wonder if I'm not getting proper vacuum into the canister or something?

[RRoller123]

I am only familiar with the FI charcoal setup, but they should be similar, although I don't think you have a sealed gas tank with the carb.... Obviously, charcoal bits should not be making their way into the carburetor. Is there some filter screen missing back at the cannister? Or maybe the charcoal has broken down from age? Not sure how to help with this one.

Maybe... What carburetor are you running? The stock 32/32 ADFA looks like this:


That spade terminal sticking off to the right there in the foreground is the fast idle solenoid. That needs 12v with ignition on, as far as I've found. This is in the vacinity of the emissions control system, so that is why I mention it - if you go tearing everything out and plugging holes/hoses, you should remember to bring 12 volts to this or the engine will idle poorly.

I'm not sure if that is the elaboration you were looking for, so let me know if there's something else to clear up.

Hey to anyone who removed your smog stuff, anyone want to donate an air pump? I'm not ready to dismantle my 77, and my air pump has an annoying rattle to it, so if you have a spare one laying around, I'll take it off your hands.

That solenoid is not a fast idle device, nor is it an emission device. It's an idle cutoff solenoid to shuts off fuel flow through the idle circuit when the key is shut off. It's purpose is to prevent run-on or dieseling as some people call it

On my 78 the compressor was removed and now I want to clean up the engine bay by removing all related parts not needed. I am sure many have done this. Detailed info on what and where located would be great. Pictures would also be a big help. I am sure there are many people who want to do this.

a officer from the government will be visiting you. removable of pollution devices violate us code.

Thank you for clearing that up - so we need 12v constant while running? I'm in Texas, so the emmisons can be trashed.

I like to keep things simple. The less in this car the better for me

Isn't there somebody that has (read: can make ) a nice DIY guide?

I would really do this but do not really know all stuf that needs to be done.
I'm happy to give it a start. Maybe somebody can add stuff in the correct order and some pictures? Because on page 1 they don't exist anymore.


1. Change manifold
2. Change exhaust
3.???

I'm looking to do this but it looks like burple removed his photos from Photobucket. Is there a better guide out there? A general comment to the moderators...good useful threads should be stickied at the top to make them easy to find.
