    EGR and Battery

    I've had the dreaded EGR 'check engine' problem for a month or more. In all that time the dash 'check engine' light has been lit, even when I've repeatedly cleared it with the scanguage, it would return within minutes of driving anywhere. I never ready got around to cleaning or replacing the EGR valve.

    But yesterday I topped up my lead/acid battery and charged it. Since then I've cleared the EGR codes (1404, 404 if I remember correctly) and they haven't returned. So fingers crossed the EGR codes might have been just a low battery problem (i guess with everything considered that value may just be current sensitive).

    If anyone has a similar EGR problem try simply charging the battery but remember to top up with demin water first.

    egr problem.
    How I fix mine.
    First took off EGR valve set it aside. Start engine and see if any vaccuum at small hole. if engine runs as usial (no rpm change with EGR removed)- there is pipe inside plenum clogged for good.
    Shut engine off.
    disconnect air intake hose.
    get throttle fully open and look inside the plenum (flexlight can be usefull)
    will see pipe on the bottom - with tiny hole ( usially sludge on it a LOT)
    getting air blower (shop air high pressure) and blow air through that pipe
    CAREFULL!! use safety glasses
    Lots of debris flying out from egr vac hole on the back-hood reflecting that stuff towards you
    put air intake hose back
    start the engine - note how engine runs(or not) with egr off.
    turn engine off. put egr back on
    clear codes, wash, shampoo engine.
    Happy wheeling))
