    The EGR valve is located at the right rear corner of the intake manifold, near the firewall. before unbolting the EGR valve, disconnect the vacuum line. but maybe the valve have too much carbon just clean with carburetor cleaner

    Thanks for the information . found the valve. no problem with nuts and vacum line however the pipe going into
    the valve is rusty and has a large nut . sprayed dw40 but donot have a wrench lare enoughn to get pipe off.
    only thingma I have is a pipe wrench and can not get on the nut. Do you know what size wrench I would need to get the pipe off? Could go and buy one. the code on my fail test was P1409 and indicsted KOER result failed
    and MIL command status failed. Any information you could provide to fix problem wouldm be of great help.
    Thanks again
