    Code P0463 Fuel Gauge no worky

    07 Yukon Denali w/193k miles Fuel gauge has started acting wonky (again). When half full or less it reads 7/8. I filled up and now it reads empty. No other issues. Probably the original fuel pump/sender module. I guess its time for a tank drop and replace pump sender module with AC Delco MU1639...

    P0300, Random misfiring at idle, Counterfeit Spark Plugs?

    07 Yukn Denali 6.2L w/193k miles. 5+ years ago I bought a set of AC Delco #41-962 spark plugs from amazon. 2.5 yrs and 22k miles ago I installed them gapped at .040". Recently, I've been getting a P0300 code and the engine has had a misfire at idle. It runs great otherwise. It doesn't set a CEL...

    Coolant Surge or Recovery Tank Hoses?

    07 Yukon Denali. I'm installing a new coolant surge/recovery tank. I need the 2 molded? hoses (part #s) that connect to the coolant surge/recovery tank. The smaller (.47"id) top hose goes to the radiator. The larger (1"id) bottom hose goes the the themostat housing area. I assume they are...

    BW4485 (NR3) awd Transfer Case Rebuild?

    07 awd Denali w/193k miles. No leaks but I think the chain is stretched. Has anybody rebuilt their Borg Warner BW4485 (rpo code NR3) awd transfer case? and did it reduce the Clunk? I've watched some videos and the job looks easy enough and parts cost is about $300. TIA

    Tired Battery=Wonky Fuel Gauge

    A couple of weeks ago the fuel gauge started acting wonky. After being parked for a while, at next start-up, the gauge would be on empty or full ? Eventually I got a check engine light and code P0462 = Fuel Level Sensor A Circuit Low Input. The battery was 5+ yrs old. I tested its capacity, it...

    Transmission Codes P0842, P0872, P0877**UPDATE**

    07 Denali w/6L80 tranny and has 191k miles, is shifting okay to me, but I borrowed a MAC Tools code reader and found codes for the tranny. So I think its time to replace the TEHCM pressure switches with seals & membranes, Sonnax kit # 124740-70K and Sonnax tool kit # 124740-TL70. @NickTransmissions

    I was Wrong - PCV and Fresh Air

    The PVC system does take in filtered fresh air. On modern fuel injected engines the source is from downstream of the MAP sensor. On a healthy engine there isn't much blowby volume, so a fresh air source is included in the PVC system to help increase air flow volume to carry away harmful vapors...
