re: How do you know if your EGR valve is working???
you can start the car and manually push up the diaphram but that is only 50/50 because the diaphram might be leaking. or yo can bite the bullet and remove it and see if it is clogged.
why do you think its bad anyway? |

re: How do you know if your EGR valve is working???
Poor mans check:
Put a piece of vac hose on the valve and suck on it. Put one finger in the underside of the valve and feel for one of the openings that goes to the diaphram and feel to see if it moves when you apply vacuum. If its working, you will feel it move and the engine will miss badly or die. Its also possible that the EGR passage that is in the intake is plugged or that the end of the EGR valve is carboned up. It could still appear to move, but be plugged. |

re: How do you know if your EGR valve is working???
1989 ford mustang with a 302, the reason for suspecting the ERG is because i had a buddy that had his valve or vaccum hose or something changed and the light went out... and i was told to check the ERG valve or vaccum hose...
that or it's and o2 sensor |
