vaccum lines eliminated

[Pro3racer]

Is there any way to tell if your EGR valve is failing, and is can i just make a new gasket ifmine is blow away. I'm on my last resorts to find a vacuum leak, and this may be it. I'm not going to block it off, because i'm a student and i need some gas mileage.

are the only vac lines that get removed those 4 that goto the tb?

Try spraying some carb clener or startig fluid around areas that may leak tosee if the idle changes,TB shaft, BISS screw, anything and everything! mark

There are 2 directly apposing arguments here and I need an answer!

So do i need to block off the fuel vent tube or not?

PLEEAASSEE???

 

[zxdude]

.. you dont have to block it off... ive had no problems

u can just eliminate those, but their is a lot more u can eliminate just look at the taboo diagram its a beautiful thing

Well, before I answer your question, I would like to know why you removed the canister. It's obvious you don't know the function if you have to ask a question like that.
My recommendation for you would be to put the canister back in and hook the lines back up the way they were.

But if you insist on making a poor decision, you should leave the vacuum line unplugged. However, you now have an open passage to your gas tank that could over time allow all kinds of nasty things inside. And since you have an open vent to your gasoline, it would be advisable not to have open flames near your car.

Installing a check valve on the line would alleviate the former problem.

Yes, that is correct. I dont know the actual function of the charcoal caniser. I just know U can take it out Sounds stupid but I can put it back on if it causes a problem. I just hate the low $$ wait. And I tinker with stuff. But I never do anything I cant fix. I just want to see what happens. Please explain....

Look into what EGR does.

A little knowledge is a dangerous thing to waste. Or something.

http://www.ukcar.com/features/tech/Engine/techno/exgr.htm

The following is information quoted directly from that link.

"EGR recirculate some of the exhaust gas (probably up to 10%) back to the inlet valve via a recirculation pipe. The amount is determined by engine ECU and controlled by a valve at the recirculation pipe. When the ECU believes the engine is running at light load, it directs the exhaust gas back to the combustion chamber. As the exhaust gas is largely non-ignitable and takes no part in the combustion process, the fuel injection can emit less fuel without worrying failure combustion. As a result, the engine still run at roughly the same speed but power output, fuel consumption and emission are all reduced."

So save gas, lower emissions, and REDUCE HP. I guess its all in what your looking for and how picky your state laws are. Personally I don't like the idea of up to 10% of my intake to be "largely non-ignitable" and intake temps of 120F on a 80F day to be combined with 1000F+ non-ignitable gas's . I think I'll put up with the slight lack of gas milage.

Just my 2cents

Also I wonder if backpressure, depending on exhuast system used, would make any difference in how much exhaust gets back into the intake track. I know it says theres a value controled by the ECU but does the EGR have a mini MAS?

Anyone has a link that works so I can check this out?

Thanks

That is, reduce hp at lower that full throttle. If you're looking for power, you should have your foot down. The EGR valve closes at WOT. I've had mine on, taken it off, and put it back on again and I don't notice any difference besides better gas mileage. YMMV

how many different ways are there to block off an EGR?

the taboo site just gives a diagram, with no explanation on anything except the function of the fpr solenoid.

i'd assume that everyone is going to throw a CEL if they do this. In my truck, i had to wire a resistor inline in front of the connection harness to the EGR valve to get rid of the CEL. Of course my truck is different than this, but they are both made by chrysler (before it was daimler chrysler) and they are both OBD1.

Not true. Unless your truck has a 4g63t in it, its different. I have had my vaccuum lines gone for about 6 months and my egr valve is blocked and no cels. If you do it right, there should be no CEL thrown. It's very simple to do. The whole point is just to lessen the chance of boost leaks.

I Forgot to say make sure u plug up the holes where the vaccum lines were on the throttle body.

sorry to bring up the old thread...but does anyone know how I should do it with the boost control selonoid still there and no mbc? the taboo diagrams show only with a mbc installed.
