No egr valve on the ve. not sure on obd1 stuff, but for the ob2 i think if you want you can pick up a egr valve and mount it somewhere and still plug it in so your ecu still thinks it there so you wont get a code, havent tried that so not 100 percent sure. option 2 you can get a resistor so the ecu thinks its not there, that worked for me so far, have not had emissions yet so i will find out in a year or so if that solved the problem. i also had a code fot the the egr temp sensor i just found one and pluged it in and it went away. hope this helps.
