Without the EGR valve you will have higher combustion temps which could cause detonation. Listen for spark knock.
Thankfully I live in a free state that doesn't require any sort of inspection or testing. Now that I've tasted freedom, I won't live anywhere that requires emission testing/inspection.
I did some testing and the EGR valve works fine. In fact it works too well. when I try to cruise at a constant speed it opens and chokes the engine causing some pretty bad stumbling. My temporary solution is to disable the EGR by simply removing and capping the vacuum line that actuates it. If I don't figure out what is causing the problem I can always wire a resistor in place of the temp sensor so I don't get CEL.

You would HATE NJ. :whipping2
I would suggest fixing the actual problem, whatever it is. The EGR is there for a reason. As someone said earlier, bypassing the EGR causes pre-detonation, which is not good for your engine.
:rofl: Funny you would mention that. My employer's HQ is in NJ and I had briefly looked at the possibility of transferring there. I concluded it was NEVER gonna happen based solely on NJ's lack of respect for the 2A (pretty sure I would be a felon there). I guess I can add vehicle restrictions to the list of reasons not to move there. It's a nice place to visit and they are also home to one of my favorite fine dining establishments; Jersey Mike's Subs! You have my condolences for living there :sorry:
:focus: I'm thinking the problem is the vacuum modulator doohickey or whatever it's called. I'll try replacing that after the arctic blasts are done and it gets warmer outside since I don't have a warm garage to work on it.
I deleted the EGR. No pre-detonation. Why would there be? All the EGR does is recirculate exhaust gas back into the cylinders to reduce the amount of oxygen.
Any logical person would ask..."why would they do that?" Answer: to reduce ignition temperature in order to prevent burning out the catalytic converter. That's why EGR was created. It never existed before the catalytic converter. Today, it's done with variable valve timing.
Lose the EGR and catalytic converters...and you'll increase HP and fuel efficency. Additionally, if you lose the PCV valve in favor of an oil catch can, you can pretty much eliminate carbon build-up....which equals longer engine life.
You can buy the kit from LG Engineering for about $20.
I live in a FREE State...I removed all three.
You’re close. EGR does introduce exhaust gas back into the cylinder to reduce the amount of oxygen available for combustion therefore reducing the temperature in the cylinder during firing/ignition and exhaust gas temps as well. The main purpose of reducing the temperature is to reduce the amount of NOx produced. It’s for emissions purposes. Not for catalytic converter life/performance.
Performance gains from eliminating the egr and catalytic converter are negligible in my opinion, but feel free to disagree. I’m not going to argue it.
