egr valve

[Jspec]

I just threw in a kl-ze engine in my mx-3 by myself. I had 3 codes come up on my engine once I got the american 626 ecu w/ mass air flow sensor or VAF from the same 626 put in. 2 of the 3 codes dealt with the O2 sensors and the 3'rd one delt with the egr valve so I went up to a parts store and got the probe gt O2 bosch sensors and I had to splice them in since the connectors where the same gender. with the new O2 sensors the constant CEL went away but I still get an "intermittent" CEL once I have been driving for a couple of miles under low RPM's. so I am assuming that CEL is from the egr valve since it goes away once I rev it up to high RPM's since the egr turnes off once I am at high rpm's or so I have read. My question is can I have my egr capped off with my "american spec" 626 ecu with no probs or can it be capped off or taken off my engine with kl-ze spec ecu? If it can be capped off or taken out with no probs with the "american spec"? if not with the the "A-spec ecu" can I bypass it with the kl-ze ecu since my kl-ze came with out an egr. If possible with the kl-ze spec ecu where could i get my ecu redone with kl-ze specs and how much would it run me?

I capped my EGR at the valve and manifold and I don't get a CEL. Though, it seems like I'm the exception on that issue...<P>Man, I need a hoist. The engine is so ready to go in.

anyone actually just run the egr? I got it mounted, but i smashed the hell outta the vac/vent solenoids, I need to pick up new ones because I live in California.

Cork sport(E.L.Prototypes) cant remove the E.G.R function un-less they have your car and the computer, and it will take a couple of days. So un-less you live in calaforia its probabley beter to come up with something else.<P><BR>If you were a good boy and got a curved neck manifold off a Millenia, you can hook up the millenia E.G.R system and it will work just fine.<P>Or if you are using an american 2.5 or 1.8 intake manifold you can just run the stock 1.8 EGR system(just remember to use the american intake manifold gaskets) you just have to transfer a small hole plug from the rear head of the 1.8 to the same spot on the KL-ZE(its on the head just under the throttle body)<P>If you have a straight neck KL-ZE manifold you can bolt your old egr system on to the new motor the SAME way it was on the 1.8.<P>BUT!!! when you bolt the EGR valve on to the back of the cylinder head dont remove the block off plate that SHOULD be there if it is a KL-ZE(Mine came with 4), you may need slightly longer bolts.<P><BR>Now hook up the connector to the top of the EGR valve.<P>This way the computer is still activating the egr and it is opening and closing the way it should and the EGR sensor is telling the computer that the EGR is working, but the exhaust gas cant get past the block off plate so you wont have any leaks at the intake manifold.

I would doubble check with cork sport.<P><BR>I sent them my computer for upgrading and one of the reasons was because they said that they could remove the egr function.<P>4 weeks later I got my computer back<P><BR>after I got the egr code on from my dash I was not happy , I called them up and after they talked to E.L. Prototypes they said that the guy that programmes the chips needed a car there so he could mess around with it and figure out what needed to be changed or removed.<P>I had asked them before I sent my computer if it was possossible and they said yes.<P><BR>Dont be suprised if your light comes on and they tell you the same thing they told me.

ok im kinda confused by curtklze's reply about hooking up my egr valve. if anyone can simplify it to retard terms i would greatly appreciate it. im going to tackle that damn egr valve tomorrow. i shall prevail!!!!!
