I had a strange and i had serched trough the posts to find some one with the same problem a screaming egr and rough running and sometimes stalling when at a light so here is my story . First i tried to replace the ignition module i imagined that i had bad sparks but no and then i went to try the TPS and .. no it did not work then suddenly i noticed a slight metallic noice from the cat. so yesterday i went hawoc on it i sawed it up and cleaned out the **** and welded it together again so now i am running without my cat. oooh i am baad. it has newer run this good .

so my problem with the egr was that the exhausts was going backwards

That may have been my post, sounds like it took me a lot more time and money to come to the same conclusion.

My '90 3.1L ran like a champ after I hollowed mine out. My gas mileage improved greatly as well, but the new plugs, wires, coils, filters, MAP, CPS and I don't remember what all else, may have had something to do with it as well.

Any way, the exhaust has a metallic "angry can of bees" sound to it now. At first I didn't care, but now it is driving me crazy, so I am shopping for a high flow cat.

Good luck to you!
Bill

i allso bought a odb1 diagnostic cable from http://www.aldlcable.com/ and now running the trial software Efilive v4 it works great but i had some problems to figure out how it worked but now it is working great.. with the definiton database "bauh" it is included with efilive .. so hopfully in the future i may be able to diagnose my faults easyer

mine is a '93 3,1 by the way

hey how did you hollow out the cat? Just cut it open grind it out then weld it shut? Or i was thinking maybe running a holesaw through the ends on a long shaft would work.
