    post-egr-removal questions

    ok, so i did the egr removal, but now the motor stalls, surges idle, and runs really rich. the idle surge tells me that i have a leak somewhere, and i think i know where that is. i got a bad hose coming out from under the intake going straight to the firewall, i'm gonna replace it. i'm prolly gonna replace the gasket between the uim and lim, cause i reused the gasket that i had when i put the upper back on. that should take care of any air leaks, cause i saw no other possible suspects when i did the egr removal.


    my question is this, once that is done, obviously the surge idle should disappear, but will that help my stalling and rich running? or are there some other things i need to do on my post-egr-removal panther?

    How exactly did you "remove" your EGR?? If you just put a pipe plug in your lower intake, you should not have effected anything...

      Resotre the EGR and fix the other problems first... Ive heard you need an EGR valve posisition sensor (EVP) "delete" device to make it run "right"

        I left my spacer, valve and sensor in place with the wires plugged in... The exhaust passage was plugged and the coolant hoses were removed from the spacer... Everything ran fine...

          You can do that, as long as there is no vacuum to the egr valve, it works. The trick is to make sure the ecm is fed a signal that indicates the egr valve is not opening. That keeps it from leaning out and over-advancing the timing under cruise conditions, which could cause issues. All that the egr eliminator plug does is feed the same signal to the ecm that the position sensor in the closed position does. Its 3 resistors inside a molded plastic plug. Mostly its for visual reasons, the little plug can be tucked into the harness so the big valve isn't hanging on the side of the throttle body.

          The EGR does not operate at idle, so no matter what you did with it, that shouldn't affect anything. The surge and rich running is probably a vacuum problem, but could be something else. Exactly what did you do to remove the egr system, and why ? Honestly its one of those few smog parts that has no real negative side effects. It doesn't affect anything under heavy acceleration, and at cruise you can sneak a little extra economy with it working.

            Did it affect mpg at all? How did you plug the exhaust passage? I might do this to the 91 when I put the HO upper on.

              Drill/Tap the lower intake for a pipe plug... You obviosly have to make sure that the plug does not stick up and interfere with the upper intake bolting down. I didn't notice any extreme mileage change.... I never drove my car easy, so I didn't worry about getting the last 1/2 MPG out of it... I still got over 20MPG with 4.10 gears (Mustang) on long highway cruises.

                i followed the step by step at the bottom of page one. the egr thing behind the tb is still there. i left the air tubes at the back of the heads, because the pipes were intact and the one way valve still worked, and i put a cap over the valve. i ran the two vacuum lines to the main egr solenoid, one to the vacuum tee at the rear of the manifold and one to the egr piece at the tb. i havent taken care of the holes in the exhaust from the air tubes, but those are down at the cats, well past the o2 sensors. i dont see how those would have this kind of affect.

                i didnt see any coolant hoses to the egr spacer. the only thing i could possibly think of besides that is the vacuum line that went from the air pump to the vacuum bit for the cruise control is still unplugged. i need to find a spot on the intake to hook it up.

                i will get the one vacuum hose replaced and replace the uim/lim gasket as well. i havent had the check engine light come on, and i made sure to follow that tutorial step by step exactly. i just have the idle surge and it runs rich as crap.

                  the coolant hoses to the egr spacer look like 1/4" fuel hose or vacuum line. Unless someone removed them, in which case there would be 2 things that look like unused vacuum ports.

                  Also, those directions are for the removal of the AIR system, which is the smog pump. This is not related to the EGR system at all. Following those directions, your egr will still work.

                      then yea, you prolly have a huge vacuum leak. You gotta make sure the red vac line that would have been supplying the smog vacuum solenoids gets plugged.

                      yeah.. I just read most of the step-by step you used... I didnt see any metion of capping the lines you removed... lol...

                        the red line went from the vacuum tee to the solenoid. i reran that with fresh hose. also reran the egr to solenoid with fresh hose. is that not the proper way? cause i am seriously getting tired of it stalling, running richer than kid rock, and having crap for power

                          ok...i just had a thought......when i went to napa and got the plugs and wires. the plugs they gave me are shorter than the ones i pulled out. i'm wondering if that is possibly leaving a deficiency somewhere.....

                          could that be the source of my bad idle...running rich....stalling....????????

                          already know the vacuum one lol

                            what plugs did you remove, and what did you re-install. if the numbers are not the same, it could be a problem.

                              i would have to look, but the plugs i pulled out are some bosch units with like 1 or 1.5 inch long from base of thread to end of spark, and the ones that went in are a bit shorter.

                              i will post the unit numbers maybe tomorrow (daylight)
