ok so as you can find out from my other threads i have been replacing the 22re in my 4runner with another 22re and i keep having problems, it will start now but the rpms only sit at like 300RPM and then the truck will sputter and die, if you give it gas it might reach 4000RPM but that is as high as it will go and it takes a good 25 seconds to get there, but if you just give it a little gas so it sits and like 1200RPM it will sit there but then the check engine light will come on and it will just die. when ever it wouldnt start i just replaced the distributor and it ran kinda but now i need plug wires,the egr is removed but im yet to plug it so there might be a vacuum leak. and today when i was just starting it and trying to get it to warm up it just kinda died completely like i was just letting it sit at like 1500RPM and then the whole engine just died no sputtering no nothing just stopped. any one got any ideas on what my problem is im begining to think its the TOYOTA on the grill but i REALLY dont want that to be the problem.

 

the truck wont run with the egr removed and not blocked off. make or buy some plate to block it or use some large duct tape strips to block the two hole off, big enough that they wont get sucked in!!! some 4" strips should do it, and make sure the hold on

 

there is just one hole the ENTIRE assy is gone, smashed........it fell off a truck......NOT MY FAULT! stupid friend tried to spin 31's on his 302 ford up a hill and it flew off and almost hit a cavy behind it. so yeah I GOT FLAMES SHOOTING OUT MY MANIFOLD!!!!!!!! it looks real cool in the dark lol, but not very safe........ill fix it whenever. oh yeah and the motor MIGHT have caught on fire.......ok i didnt know antifreeze was flameable but it is yeah a coolent hose blew off and soaked the manifold and wosh it was on fire so me and one of my friends tossed snow on it and kinda passed out from the fumes..............yeah tell me off later. so yeah help me please, do i stll need to plug the egr hole thingy??? i hate emmisions, the enviroment can take one more for the team its just a 22re its not gonna like blowa massive hole in the ozone above PEI. oh and another thing if you live on PEI and your rig is a 1991 and under you dont need your emmisions equipment yay!! lol.

 

it wont run with any holes......holes=vacuum leaks. and if the egr assambly fell off, there would be 2 holes....one in the head (rear passenger side) and one at the back of the intake

 

where is the one on the head i can only see the one on the intake.

 

its on the passenger side at the back of the head (not ON the back, just at the back) kinda hard to see if you dont have good light

 

alright now i need 2 big bolts instead of 1.

 

oh and one last thing would a header still have the egr ports like on the stock manifold or does it block them off??

 

the header would be on the drivers side. and you sure you know what the egr valve is and where its located? it goes from the head to the rear of the intake manifold

 

Those ports on the exhaust manifold are actually for the PAIR system.

The EGR goes from the head to the rear of the intake plenum.

 

EGR= Exhaust Gas Recirculation, it wraps around and attaches to some stuff which leads to the EGR but is gone so there are 4 like 1/2 inch holes in the manifoldthat shoot flames and make it EXTREAMLY loud. what is a PAIR?? ugh i hate EFI I WANT A CARB!!!!!!!!!!!!! so much easyer.

 

ok now i understand yeah i know what the EGR is i have NO clue what a PAIR is. i just assumed that that is what the big golden looking tubes were for.

 

PAIR- Pulse Air Injection Reaction. You know that small tube that goes from the airbox and wraps around to under the intake manifold? Thats part of this system. Air goes through this tube to the AS Reed Valve, then snakes around behind the engine through that copper looking tube that attaches to the top of the ex. manifold. . The Venturi effect of the exhaust gases pull clean air into the exhaust, speeding up oxidation in the cat and the rest of the exhaust.

 

are you sure cause the exhaust gases are pushing pretty hard and i thought it was the oth way around the exhaust gases went up thru the weird tube ste up and in to the intake AKA EGR i have never heard of this PAIR system, but then again im only 3rd year MVR in high school.

 

Yes I'm very sure. Of course if there is nothing covering the ports, exhaust gas will be shooting out!

 

yeah its pretty cool looking even better at night the flames are bright blue!!! but yeah i gotta get them covered over, will it run ok without the pair system?

 

anybody??

 

well obviously it won't pass emissions. The exhaust might get hotter than what it normally does so you will probably damage the O2 sensor. Your O2 sensor will probably read a rich condition, which will tell the ECU to trim the amount of fuel, so you'll probably feel a loss of power. Your cat will probably get fouled up. Also, the engine will probably run a little hotter without the EGR stuff.

 

i lived on pei its in canada we dont have emisions testing and you dont need any of the emisions systems if your rig is 1991 and below, i have no cat

 

Not sure why you'd remove the EGR valve... if you don't want the EGR to work, pull and plug the vacuum line off of it and *poof*... no EGR... and no exhaust or vacuum leaks to worry about plugging.
Just my dime's worth (used to be 2 cents but the increased cost of living caused me to raise the price, that and the increases in tobacco taxes)....
