    OEM parts on Amazon?

    Good luck with it, Tony! Hope it un-breaks the brakes! ;)

    Rear Climate Control

    If you think it's the Dorman one it should have a lifetime warranty, so you could return it to the seller and have them give you a new one.

    Normal oil pressure for 03 l59

    My '04 L59 with 114K on the clock runs about the same at hot idle. I recently had the oil pan gasket replaced and had them change the o-ring. Didn't make any difference in the pressure, but you know, while they were in there... the old o-ring came out somewhat hard so I'm glad I had them do it.

    Crank position sensor relearn procedure?

    It should be fine, but have it done if you experience unexplained random misfires.

    Reman engine no start than start with detonation.

    Off topic: If that's your real name, would you be related to Bill, who produced musicians like the Eagles and Joe Walsh?

    Reman engine no start than start with detonation.

    Which engine? Flex Fuel or not? Make, model, year? If it's consistent and you know it will crank-no-start when hot, try using clear flood mode. Hold the accelerator pedal to the floor to turn off the injectors and see if it will start first try. If it does, suspect a leaky injector or a bad...

    Location of the fuel tank pressure (FTP) sensor for a 2005 Yukon XL K2500 6.0

    Post up the last 8 digits of your VIN and maybe @915_Tahoe would be able to look it up for you, see what the part number looks like.

    Location of the fuel tank pressure (FTP) sensor for a 2005 Yukon XL K2500 6.0

    Weird thing about that photo is it shows #1 but not #2 and #3. Kinda doubtful that #1 is the "fuel pump." Whatever it is should be mounted to the rearward side of the crossmember with two hoses connecting going forward.

    Location of the fuel tank pressure (FTP) sensor for a 2005 Yukon XL K2500 6.0

    I searched the link that @strutaeng posted and found 5 occurrences of "fuel tank pressure sensor" and this was the only diagram that came up. Not sure if that helps.

    Wow great mpg

    Moved this thread from the EV section to the Duramax Diesel section.

    Slight miss at idle, poor MPG, sooty exhaust pipe, No codes. 250K

    Show us the short- and long-term fuel trims and what the MAF is reporting in g/s at hot idle.

    Misfire engine

    Sounds like you have a warranty on your (new?) engine. If they'll make you whole, then go for it.

    Misfire engine

    Or a valve spring, bent pushrod.

    Misfire engine

    If they gave you a written explanation of the diagnosis it would be great if you could post it for us to see.

    99 Tahoe 5.7 vortex P0300 code HELP

    Is your warm engine idle 800 rpm? 30° C is not quite 90°, so the idle should come down after being fully warmed up. The higher idle in your readings will affect the MAF reading. The MAF may be over-reporting the air that is coming in, but the engine needs to be at operating temp and at a good...

    Leaking exhaust manifold

    It should be fine unless it's still leaking after being warmed up. An exhaust leak can cause a lean condition and the engine computer may richen the fuel mix to compensate, causing catalytic converter failure down the road. Fuel trims would indicate if that's happening. YMMV

    Doubt you'll get a response from the OP, who hasn't been on here since April.

    2013 Yukon Denali Hybrid AFM Delete won't pass emissions

    Hit the link below and scroll down to the drive cycle details in post #3. There are some very specific conditions (fuel level, ECT vs IAT absolute and delta, etc.) that need to be met for the cold start and if those aren't met, nothing's going to happen...

    IMPORTANT: The Chronicles of Low Oil Pressure by 07burb

    Which engine does it have? (What's the RPO code?)

    Synthetic vs conventional

    At 142K I suspect that there's some oil being burned. How much, only one who tracks that would know.

    Parking Light on When in Drive

    The DRL harness connectors tend to get hot and scorched, so that's a potential source of a connection problem. The stock DRL bulbs are two-filament but only one filament is used. I could never figure out why that is, unless they don't make a single filament bulb that GM wanted to use.

    Throttle fault code P2135

    To add, if the code is there consistently, and it's convenient, get a snapshot of the freeze frame data. That should show the PIDs that are germane to the code.

    Throttle fault code P2135

    Any that have to do with throttle position (pedal, throttle body, etc.). There should be sensor data as well as PIDs that compare them.

    Throttle fault code P2135

    Have the various position sensors been graphed to see if they compare properly with each other? This would be with a bidirectional graphing scanner, looking for inconsistencies and dropouts.
