Egr
Just tought that I share this...
Has anyone that have the 3VZE with the EGR equip done this? I have decided to cut the tube that goes into the air chamber because it seem to be blocking the air flow inside the air chamber so I cut that piece off, and yet to have no problem diong so, it accelerate better, and higher rev. The EGR system is throwing a code 71 which I use the 1k ohms to trick the ecu and it had help alot without the code 71 so since I think I am having a bad egr system I decided to cut the egr tube that goes into the air chamber. If anyone that is interest cutting there egr tube that goes into the air chamber off then you need to take out the egr part out before diong the cutting, I use a hacksaw w/ metal type saw to cut mine..

Good ? I do know why it would improve performance, very slightly. No more airflow diturbance as it flows by that pipe. And a very, very tiny increase in plenum volume. Gutsy move from a Californian, messin' with the EGR.
Coincidently did the same cut-off job on mine. Went a step further, for a much more signifigant performance gain. Tip: Put a stopper in the end of the pipe, where just cut. This ain't legal where your at I assume, so don't blame me.

I mean, since I am having the code 71, I will go ahead and cut that piece off and if it have any problem while that piece is cut then I will just buy a new egr system, but it didn't have any problem..
Just last week, I did my smog check and it pass, my test was lower than the average requirment to pass the CA emission.

can you not make block off plates and block off the whole system? I just replaced my egr valve last week and thought about blocking it off but I didnt know exactly what would happen.

What happens is a better performing engine. The EGR has only negative effects on an engines performance. If you don't have emmissions testing where you live, and don't have any guilt for contributing to global warming by doing so, by all means do it. I don't imagine it'll be long before they make us all (I have done this on my engine,too) have a working EGR to operate our vehicles. I did just as the pics. show, above. Then inserted a 1" rubber stopper in the end of the pipe(cut-off point). You'll see and imediate change in how she runs, I noticed 2-3 maybe 5 more mpg! Which is an easy excuse, too. Think less gas burned, more mpg, less emmissions all together, right?

No, you can leave em to do there thing. The system shouldn't register any change. Theoreticaly you could pull the hose at the top of the EGR and plug that hose. It would be a less extreme way to do the exact same thing, EGR by-pass.

You could be right, sounds poss. ta me. Trade-off? I'll swear about the performance gains. Thanks, hadn't heard that one yet. I'm hurtin' my brain tryin' to figure it. As far as I know Exhaust Gas Recirculation. Means that ,exhaust back into the engine, exhaust bein' HOT, I'm beginin' to think your just pull'n my leg.

Dont hold me to it but it allows the hot exhaust to warm the air entering the motor to allow for less knocks and pings. too much hot air at idle makes it run rough because the fuel almost explodes instead of burning cleanly. but at higher rpms the valve doesnt make that much of a difference.

Yep! thats why i said dont hold me to it! it doesnt increase the air temp it increases the combustion temp!

Also as for being concerned about CO2 emissions and global warming. Isn't an old EGR valve about as effective as an old catlytic converter? It helped reduce CO2 when the vehicle- and those parts- was brand new, but at 200k+ miles they have long lost their effectiveness. Right?
