1. Smog pump removal with hoses and get a shorter belt 835K6 2. Unplugging the sensor on the back of the passenger strut tower 3. Unbolt the smog tubing from the h-pipe 4. Unbolt the smog tubing that goes to the heads and plug the holes with plugs 5. Unbolt the EGR valve and make/buy a plate to block the holes to the EGR spacer 6. Plug the vaccum line on the back of the upper intake 7. Unplug all the vaccum hoses from the passenger strut tower to the EGR to the intake 8. See EGR Deletion for last step |

The sensor on the back of the EGR that tells the computer when the its open and closed. My friends car check engine light works mine doesnt so i tested it on his car. If you unbolt the sensor from the back of the EGR valve there is a plunger that goes in and out that tells when its in closed loop and in open loop. When you pull the sensor out the check engine light comes on bc the plunger is all the way out. Closed loop on the EGR valve is about a 1/4 of an inch push in bc when you put the sensor back in the valve it pushes on the metal plate inside the valve about an 1/4 of an inch. So also the way the EGR valve works is idle-part throttle the EGR is open and at WOT the EGR valve is closed. OK knowing that at WOT (Wide Open Throttle) that is a lot of vaccum so the vaccum would pull the metal plate inside the EGR in and push the plunger on the sensor in making it go into closed loop. Anyways if you dont want to know about how the EGR works dont read above all. It says: Unbolt the sensor from the back of the EGR valve and push in the plunger about half way and tape it there now the sensor will read closed loop. DON'T PUSH IT ALL THE WAY IN JUST HALF WAY!!!! Now you can get a EGR block off plate for the back of the EGR Spacer and get rid of the EGR Valve itself now. |
