the egr passage was completely plugged, i had purchased a new egr valve anyway,since one of the coils wasnt working using the test,(thanks slam2316) from this site on the y shaped pins. anyway, i used a "bore snake" of a .22 cal size and it was tough to get through, just kept on spraying and pushing and scraping,i read the how to by mikem220153 and i thought no way could a .45 snake go through that passage way, so, being the stubbern guy i am , i bought a .45 cal snake as well and it got jammed as soon as i started to fish it through, so i sprayed and hacked some more, for about 1/2 hr, then i tryed the .45 and damn it was stiff, was afraid it would get stuck. but in the end got it through. cleaned up for about another 1 and 1/2hrs then popped on the new egr and buttoned everything back up, took it on thte highway for about 20mins and decellerated quickly couple of times, NO LIGHT, wohhoo , thanks alot for everyones help here, i probably could have ran the car with the light coming on every so often but i am anal about my cars, and i wanted to fix it right. without this site i probably would of spent untolds amount of money on this egr fix, i dont think a mech at the dealer would of been so thorough on cleaning the passage way as me, if he would clean it at all!, so i just want to say thanks to everyone who posted what to do. btw my car is a 94 grand am se 3.1, and the pin layout for the obd is different than the pin layout for either OBD I or OBD II, i thought i read on this site, that mine may be OBD I.5,,is there anyway to erase the stored codes in the computer, without going to the dealer, i hate to pay $80.00 for them to work on it for 5 mins, when for some more money i could buy the scanner(maybe) or i could just unplug the battery for 15mins, does anyone know for sure what to do. thanks again johnny.
