    Wound up buying 2 new Dorman replacement IMRC's
    was gonna try this myself, but theres a lot of stuff to remove to get at
    them.

    Dropped it off at a service station, he says there are (12) 8mm bolts that hold the plenium
    to the intake and they are corroded pretty bad, cant get any of them to turn without the socket stripping
    the head of the bolts.

    Not much room to work a drill in there for an EZ-out he says, so hes putting it back together
    and I will I guess try and hunt down another shop or maybe try it myself.

    I did buy this purge valve and had a mechanic put it in while he tried to replace the IMRC's.
    He says the 8mm plenum bolts are stripping as he went to remove them, so he gave up
    claiming he would do more harm then good but after he changed the purge
    valve, theres
    clearly an improvement. Apparently that supplies the vacuum to the IMRC's
    and the idle is better
    and the sluggishness at 3000 RPM happens a lot less often.

    I thought about trying to remove the plenum myself and use one of these https://www.ebay.com/itm/226884149548

    But I dont know if there is anough room in there for it to fit, says it will grip an 8mm
    head or stud.

    Also , after the mechanic replaced the purge valve, the check eng lite is
    on. Will reset
    with OBD, but returns later with the 2 error codes plus a new one
    referencing the EGR system.

    Another video claimed replacing the Vacuum Solenoid Purge Valve , PN: F65Z-9H465-CA /
    F65E-9H465-CA solved the 2 error codes so I am thinking about buying this one on ebay:
