I have my Wits End keychain enroute and am curious what people have done or which guide people followed. I see a couple in search. Don't care if CEL is on, I just want to dump all the clutter and massive heat dump by cylinder 6.

I will figure it out but just curious what those that did the delete have done.


Thanks.
 
I deleted mine when I did the head gasket in Feb. Put a set of Genie headers on at the same time and they have no EGR provision. I simply capped the 2 vacuum lines off and it runs great sans EGR and cats. Do want to add back in a cat though and re-install the after-cat O2 sensor. CEL is on, but I do aim to turn that light off with the resistor mod on the temp sensor and a cat.

Btw, cylinder 6 is where the head gasket went out. So typical.
 
I removed my PAIR system and deleted my EGR system. I went fancy with a sawzall and used the high temp kwik steel to plug the hole because I couldn't get it unbolted. I used a jumper wire to short out the EGR plug and wrapped it in fancy electrical tape. Haven't gotten a code 26 since.

On the spare 1FZ-FE I'm SLOWLY rebuilding, the first thing I did was take the EGR off and throw it in the garbage. Then took off the PAIR system and threw it in the garbage with it.

There is no way that it is purely coincidental that the HG almost always fails at #6 with the EGR dumping hot exhaust in right there.

No coincidence that HG failures in AU engines are very rare. Luckily I don't have to delete the PAIR crap, just the EGR......saves more room in the trash for my fender flares.
 
I deleted my EGR a month and a half ago. More power and better fuel economy. I then replaced my o2 sensor and my fuel economy went to s***.

I made two block off plates out of scrap steel and reused the bolts that held the EGR and tube. I plugged one vacuum line with a large nail and looped the dual lines. The absolute worst part was reaching into the very small cavity by the base of the tube and loosening and tightening the bolts. My forearm was sore for days afterwards. The PHH which is to the left of the base of the EGR will be much easier to reach when I replace it. I have a the EGR assembly out in the garage if you need a picture.
 
Have a friend 1993 fjz80.. Cat deleted/Egr/Pair.. No cels over 100k deleted.. Total of 270k on original motor, runs like clock work..
 
I just pulled the wire connection apart, made a nice jumper wire out of romex and wrapped each end in heat shrink wrap and doubled the vacuum lines back on each other. I have OBDI though and that was all it took. I love not having that angry pipe heating the piss out of my wire harness and head gasket. Seems totally unnecessary from a performance standpoint.
 
If your truck is OBD1, then you won't have a CEL. If it is OBD2, you will be running in a "limp mode", without the diode to trick the computer into thinking it is working.

That being said, I deleted mine on my 94 a while back. I suggest finding a small flexy head wrench and a short 12mm socket (I ground one down to fit), because it is a tight awkward fit between the firewall and the engine to get the EGR tube off....

Deleting the rest of the system is very easy. I took the upper intake manifold off for ease of removing parts. Currently I have my evap can venting to the atmosphere through a small fuel filter. This is a temporary fix until I get back in there and route it back into the engine via vacuum.

Yes I have a '96 so OBDII. I'm looking to remove everything I can and use block off plates. No inspections here anymore so I don't need to keep up appearances under the hood. Thanks for the tip on getting the EGR tube off. I am taking upper intake manifold off as I'm going to change fuel filter at the same time as well as that other PITA coolant hose under there.
 
Removed mine with block plates and the resistor added for the CEL. I feel like there should be more of the stuff under the intake that could be removed now, but have never sorted it out. 1996 model, runs fine for several years since doing it.

Kaninja,

Can you explain what you mean by "massive heat dump by cylinder 6"?

Not sure I understand...Thanks

Well the EGR pipe back there gets crazy hot. Sometimes leading to the deterioration of the wiring harness that is nearby. Also, these engines were designed sans-EGR. Only North American 80's had EGR added. Also, I believe the common HG failure at cylinder #6 may be caused by the EGR system.

Yes the EGR pipe does seem to burn the harness as seen by so many here. Not sure I understand how it leads to HG failure though. The EGR valve, when open, allows those exhaust gases to flow to the top of the upper intake manifold thru porting in the manifold feeding all 6 cylinders with a bit of the exhaust gases.

Just wondering...thanks

It's coincidental but highly suspect.

I don't understand either, but it sure seems to happen a lot at #6. It is much more rare for non-EGR 1FZFE's to have failed HG's.

Anyway, it just isn't a good implementation of EGR on these engines.
