I guess i'm mostly an ethical/responsible car enthusiast. Any car that isn't a trailor queen should have a CAT on for instance...

I don't know how much gas fumes can do or how it helps, but it'* there for a reason.

I believe its there to clean the vent fumes from the gas tank. Im sure after a few years it loses its effectiveness anyway.

It temporarily stores excess gas vapors from the tank so that they do not vent into the atmosphere. It helps improve ambient air quality.

so basically if you do not have emissions tests it is not needed

Heh, the local inspection is checking that the lights work, the tires are good, the brakes work and the glass isn't cracked.

Well sounds like I'm not being ethical or resposible by removeing it.


Anyway, this would also allow me to run any tb that was originally on a series 2 with a 4t65.

Personal experience as of this point shows that there are no negative side affects to removing the canister. I asked Scott Cook some time back and the general consensus was that I would have no problems in removing it, so I did to make room for a FWI. It WILL throw a code if you simply remove it because there is an attached selinoid that has a required 2 wire connector. I unscrewed the selinoid from the canister and mounted it by itself and mocked up a bypass with some parts from a local hardware store. After I did the bypass the check engine light turned off and hasn't been on since.

My opinion. If you are removing it for performance reasons (mainly a FWI) then by all means give it a go, but to remove it just to remove it is without reason.

As for the EGR, keep it unless you have an intercooler.

Just a friendly FYI

Gasoline evaporates quite easily. In the past these evaporative emissions were vented into the atmosphere. 20% of all HC emissions from the automobile are from the gas tank. In 1970 legislation was passed, prohibiting venting of gas tank fumes into the atmosphere. An evaporative control system was developed to eliminate this source of pollution. The function of the fuel evaporative control system is to trap and store evaporative emissions from the gas tank and carburetor. A charcoal canister is used to trap the fuel vapors. The fuel vapors adhere to the charcoal, until the engine is started, and engine vacuum can be used to draw the vapors into the engine, so that they can be burned along with the fuel/air mixture. This system requires the use of a sealed gas tank filler cap. This cap is so important to the operation of the system, that a test of the cap is now being integrated into many state emission inspection programs. Pre-1970 cars released fuel vapors into the atmosphere through the use of a vented gas cap. Today with the use of sealed caps, redesigned gas tanks are used. The tank has to have the space for the vapors to collect so that they can then be vented to the charcoal canister. A purge valve is used to control the vapor flow into the engine. The purge valve is operated by engine vacuum. One common problem with this system is that the purge valve goes bad and engine vacuum draws fuel directly into the intake system. This enriches the fuel mixture and will foul the spark plugs. Most charcoal canisters have a filter that should be replaced periodically. This system should be checked when fuel mileage drops.

I also agree with Allmachtige that I'm not a big friend of EGR removal without taking proper steps to control detonation.

there'* a reason that we have a sticky at the top of this forum on 1992 egr-less motors...

Very good points here. Both about the EGR and the Evap canister. Both will throw codes if you remove them, as already stated. The EGR delete will burn valves over time, and the evap will gain you nothing by deleting it. Relocated, don't delete.
