    01 5.3 P0300 after changing plugs/wires

    Same ac Delco part number as the dealer? I would find it very odd if a retail store sold counterfeits (Amazon I’d expect it nowadays)

    Intake Manifold Nipple Broken! Please Help

    I "think" that's the fresh air connection to passenger side valve cover. The driver side valve cover has the pcv valve near the firewall and the pcv hose goes to the top of the intake, at least "this is the way" on my 02 Yukon ff5.3

    REAR END UPGRADES

    The two vs one rear break line I "think" has to do with stabilitrak vs not. Nothing to do with rear pumpkin size.

    2001 Tahoe 4wd theory

    My 2002 has no traction control, and abs is not involved in the auto 4wd operation. It's purely mechanical based on the np246 transfer case's clutches.

    Exhaust joint gasket - y pipe to muffler?

    Thanks for chiming in! thats an N of maybe 5 Now. The ball and socket makes sense based on what I see on mine.

    Exhaust joint gasket - y pipe to muffler?

    Well, I've seen a lot of parts diagrams, mostly aftermarket, and the pictures seem to imply there should be a gasket there. I saw a post where one guy had an avalanche, gen 3, who did not have a gasket there and one other person agreed that there's no gasket, but this is a really low N number...

    2004 Escalade ESV Fuel Cap Issue

    Are you using OEM gas cap? After 22 years and 3 replacement caps, cannot beat OEM for NOT having errors (assuming you don't have something else wrong);

    Exhaust joint gasket - y pipe to muffler?

    Happy St Patrick day! 2002 Yukon 4x4, 5.3 FF. 224k miles. The exhaust connection right after the Y pipe, to the muffler, drips condensate while the engine is warming up. Is there supposed to be a gasket at that connection? There's only 2 bolts. A shop changed out my Y pipes a few years ago...

    Coolant Tee Quick Questions

    If the OP has rear heat, I believe the angles are different between the black and white tees. I don’t think a black T in place of the white one would work.

    Black smoke

    What brand of O2 sensors? You have any old data to share? Fuel trims, misfire counts etc. yes, I see that you corrected the misfire in 4 &8, but are you sure? Just trying to help, not question your work.

    Slow 1-2 and 2-3 shift?

    Smarter folks will chime in, but everyone who's trying to help going to want to know how many miles on the drivetrain, has anything been replaced, and with what brand? Also, when is last time you cleaned or replaced the throttle body and mass airflow sensor? The MAF does influence transmission...

    Long term and short term fuel trims intake leak, low idle, improving fuel mileage. Mpg

    I think it's best to take a MAF reading when it's warmed up, but the values for idle that you posted 0.6 3 lb per minute is about 4.8 grams per second. That's just slightly on the low side, especially considering your RPM is 602. My idle typically sits, after warmed up, round 550 to 560. I have...

    Long term and short term fuel trims intake leak, low idle, improving fuel mileage. Mpg

    What does your maf read, in g/s, at idle? How old is the maf? The general consensus seems to be that the maf starts crapping out around 140k-160k miles without throwing codes.

    High FT diagnostics with sprays

    Well, I've been silent on this topic because summer came and the problem went away. Fuel trims back to normal. Then winter came last month and fuel trims went up again. So cold weather makes it look like I have a vacuum leak. I used a nice flammable spray like throttle body cleaner when it was...

    Intermittent Start - SOLVED

    As others have said, bidirectional scan tool would be quite helpful here. IIRC, cam position sensor could cause similar symptoms?

    Transmission cooler to radiator connection question

    I thought the new radiator did not have transmission fittings? Or maybe I misunderstood...what are the pipe fittings you're referring to in the first post?

    Please Help Me Find Water Pump Bolts ... Also, Leaking Oil From There?

    Water pump bolts need torque to yield and go through water jackets? I don't remember this at all. Man my memory sucks. Is a 2002 yukon 5.3 FF different?

    Airbag light and parking brake

    Check ground point under driver's side near A pillar, chassis extension....couple of ground wires attach there and the parking brake cable routes nearby. Others will chime in that know much more. Lots of threads about ground issues

    p0128 Engine temp below thermostat temperature/ strange O2 sensor values

    I'm starting to wonder if your propane setup just runs at a different temp and exhaust gases are different. Although your PCM is tuned for propane, are the sensors specific to propane or just regular O2 sensors? This is what we call a WAG...Wild A$$ Guess
