egr tube

What problems? All you need to do is put a blocking plate in it...











This was for MY '08 V6, but the principal is the same.

The only problem you should be having is a vacuum leak. You will get a check engine light, but it won't
effect how the car runs. It will run a little hotter, more complete burn, maybe little less MPG, more NOx.

Diesels benefit from an EGR delete; gas motors hardly at all. There really is no reason to delete the
EGR in a gas engine. The EGR closes at WOT anyway, it's mostly for idle and warming the car up faster
from cold.

 

The CEL Blinking is not EGR related, that's misfires. Just might be a total
coincidence, since it happened a few days later. Can be bad plugs, to coil
coil pack(s). See which cylinders are misfiring.

For EGR, all you needed was a blocking plate at the engine side. Deleting
it means removing all the parts associated with the EGR system. A block
plate stops the exhaust gases from entering the engine the same as taking
the tube off and blocking the ends. More work, more hardware, same result.

If you are 100% blocked at the engine side, then it isn't the EGR deletion
that causing it. A vacuum leak through the EGR system would. That is
why, when an EGR sticks open, you have a bad idle, and poor performance.
Better to stick closed than open... So, if somehow your deletion has cased
a stuck oepn type condition, then there is your problem, else, the misfire
is not related.

 

You May have to have your PCM re-flashed to compensate.

Removal of EGR system: performance gain or loss?

 

I ran without EGRs all the time, and never have had to tune the car. All the EGR
delete does it raise combustion temps since there is more exygen -vs- exhaust
gas mix, thus raising NOx gases. I ran my Mustang without it, and I saw a 1-2
MPG reduction, so I unblocked it. I ran it blocked for a week with no adverse
effects, just the check engine light for flow rate.

If the reductions of NOx was no longer an EPA mandate, you would see the EGR
disappear from newer cars after the legislation... They do nothing but reduce
NOx emissions. You can get some unburned gas fumes, and they are reburned
but it's only on ONE side of the engine anyway, so why bother. Nope, just for
NOx emissions.

You will just need to run higher octane if you get detonation without an EGR.

 

What I mean by that, is many times you will get a CEL, and the only way to get rid of it is to program the PCM to disable that EGR program.

 

They call this TUNING out the effected system.

...And again:

Having no EGR is not causing his issues as stated in quote#1, UNLESS he has
introduced a vacuum leak doing it, or intake air getting in behind the MAF sensor.

A blinking check engine light is a misfire, if his is EGR related, it's vacuum leak.

Lean misfire
The lean misfire is another common reason for an engine "miss" — this is due to an
imbalanced air-fuel ratio (too much air, too little fuel). Since an engine needs a richer
(more fuel) mixture for a smooth idle, this problem may be more noticeable when
the vehicle is idling.

The lean misfire may decrease or disappear as the engine speed increases because the
efficiency of the volumetric flow into the combustion chambers increases dramatically.
This is one reason why a vehicle gets better mileage on the freeway than in the city.
An EGR valve that is stuck open, a leaking intake manifold gasket, a defective mass
air flow sensor, a weak or failing fuel pump, or a plugged fuel filter are some of the
many causes for a lean misfire.

AS I SAID, he may have a vacuum leak, or created the stuck open condition with a bad
blocking plate gasket. If it's not EGR related, then it's mechanical, or electrical. He needs
to go over the blocking plates, and vacuum lines. You do not need a tune, there is
a leak or something else.

I don't read or write Spanish, anyway.

 

We know it sets a code, I said it does. It can be plugged in, blocked, will have the inecfficient
flow. Unplugging it causes all the other codes. With the 2005+, you can't unplug it
because the MAP sensor signal wire is there as well, so you will get a LOT more codes
on a 2005+

 

How much POWER do you get?
Is your car going to gain 600 HP?
6 seconds in the quarter mile?
It's there for many reasons and not worth arguing about.
The so called gain is negligible, another urban legend.
Other people will tell you, it's not like a real power adder.
The gain, if any, is very little.
This who EGR issue goes back to 1968 when it and air pumps were factory installed.
But, people will do it anyway, setting codes, and polluting the air.
EGR actually helps with mileage also.
So, believe what you want, a lot of people a misconceptions they worship.

EGR Delete, Why and How??? - Forums at Modded Mustangs

 

I basically said that already.

However, you can bet, if we did not have emissions, the EGR would NOT be there.
In fact, it wasn't, then the EPA came along, and there you have it.

I removed the blocking plate, it made no difference, and I said as much, not here
there was no point in posting the whole tutorial when I removed the blocking plate.
I still have it if anyone wants it...

 

The Earth is flat.

 

As are some people's heads...

 

You ought to get that looked at, maybe a little reconstructive surgery will work...

 

My thoughts exactly, you're like a mirror...

 

Ooh, I am sorely wound, loser.
Hard headed loser.
