Okay, I've been having trouble after trouble trying to get my EGR to work, so I was just wondering somethign.... Could I just delete it and get it over with?

I'm lucky enough to live in a place that doesn't have emissions tests to worry about, so I was thinking that I could just snip off the tube from the EGR and plug it with some cold weld, remove the EGR and screw a plate over the upper intake vent, then plug the vacuum line and forget about the whole thing.

I heard that it would make my engine knock due to the higher combustion temps, but I also heard that someone here did the same thing. Do you get better milage and power? Is it a good idea to do if I don't have emissions to worry about? Will my check engine light stay on because of that?

(I was going to swap in a ranger header... But I've run into money problems and I'm nearly broke. If anyone has one they're willing to part with, I'd be happy to take it off your hands for the shipping cost, though...*hopefull dreaming*)

It is much easier than you think. Simply pull the vacume line off the EGR and plug the hose (so you don't have a vacume leak). The EGR will be disabled without a vacume source. It may throw a code, but it will never be able to open. If you want to be fancy, then yeah you could remove the EGR tube and valve.

How does it effect the way the engine runs?

Better power/milage?

Does it increase knock?

Other than screwing emmissions, what does it do to disable it?

I doubt you will notice any difference with it disabled. It does reduce the tendency of the engine to ping at light loads, but these engines arn't very likely to do this. You could theretically notice worse milage as well, but I doubt you will.

All in all, you won't notice it unless you check for codes.

Check Engine Light Code 332

Biffmeistro,

I don't know if you have already blocked your EGR off but you may want to read the info I found in a tech manual. Pay special attention to the NOTE at the bottom.

You probably will get an engine light for code 332, insufficient EGR flow. I am currently having a problem with code 332 and the EGR valve after doing the Ranger Header swap. I haven't noticed any drivability issues and haven't had the problem long enough to know if milage has been effected.

Description and Operation

EGR valve position sensor




The EGR Valve Position (EVP) sensor returns a voltage signal to the Powertrain Control Module (PCM) indicating whether the valve is opened, closed, or somewhere in between. The voltage signal is in direct relation with the valves movement. The sensor is a linear potentiometer mounted on top of the EGR valve.

NOTE: EGR closed position is very important. Timing is retarded if EGR flow is low.

Hope this helped.

Agreed there. If the engine control computer is not receiving EGR valve position signal, it will automatically retard the timing so it won't ping. I was having major EGR issues with my 88 stang when I bought it and after I got it working, I enjoyed slightly better cruising power and better fuel economy. I replaced everything in the system- valve, sensor, controls, even the vacuum reservoir (that had a hole in it). What problems are you having? I've had lots of trouble with mine but got it all solved.
