    Jack it up and shake everything hard. Also, check the wheels (axles) for play up down in out

    Major FLAW discovery with Electronic throttle control with MAP sensor equipped engines

    Ya know, I heard a guy say one time that, even though GM put MAP sensors on MILLIONS of vehicles, that they’re totally not required. You should probably just take it to Pep Boiz and have them take it off and it’ll solve all your problems.

    07 5.3 Knock Sensor Issue

    What brand knock sensors did you use? Did you torque them to spec or crank to tight enough?

    Tensioner pulley moving too much

    I’m not against replacing pulleys, but i’m more ‘for’ maintaining them before they go bad. I pull the seals and grease them when they’re new—there’s not much grease in there to begin with—and they last a LONG time with enough grease.

    Tensioner pulley moving too much

    It could be. Take the belt off and give it a wiggle. While you’re there, you can remove the pulleys and pop the seals off the bearings in the idler and tensioner pulleys with a pick or the pointy edge of a razor blade. Dab some grease in there and snap the seal back in place and reassemble...

    2007 Denali wont start after cylinder head replacement

    If the battery was completely dead, it’s probably garbage. When you get your starter checked, get your battery checked too

    A/C Belt

    ‘07 should have a tensioner If you’re changing the belt, do yourself a favor and pull the tensioner pulley, use a pick or the edge of a razor blade to pop the seal off, dab some grease in there and snap the seal back in place.

    YouTube must save us Billions

    The billions saved via YouTube is offset by the helpful citizens of Facebook groups. People are constantly asking about stabilitrac or CEL and half the yayhoos suggest the part that fixed their issue. Original poster comes back the next day and says “welp... that didn’t fix it...”

    Cylinder 1 misfire check engine light rough idle

    There are almost an infinite amount of things that can cause a misfire on one cylinder—unless you just have money to burn, don’t use autozone’s suggestions for what you should buy. As someone suggested, swap it with another coil and see if the problem stays or follows.

    Engine idle issues still part #2

    So all the automakers have been putting MAP sensors on millions of non-supercharged vehicles all these years for nothing? I mean... they don’t use that signal to help determine load and adjust engine parameters or nuthin’? Are you sure about that?

    Engine idle issues still part #2

    When you do, pull all the covers they probably shouldn’t be going into and put love notes that say stuff like “what are you looking in here for?” “NO TRESPASSING” and “Surprise Muddafukka!”

    AFM yay or nay?

    I have a Range Disabler and will run it until the day the motor needs a rebuild, at which point I will replace the AFM components with non-AFM. Yes, I would purchase it again but I’d do it as soon as I bought it instead of after my first AFM lifter failure.

    Error Code P1175

    Do these engines have AFM? If so, #6 is an AFM cylinder and it could be the valves are gunking up as a result. I had the passenger head off my 5.3 for AFM issues (#4) and I could stick my finger into the intake port and there was sticky oily gunk collected on the short side of the runner just...

    08 Tahoe ltz afm or fuel issues??!?

    OP talked about EGR and then replacing parts in the back by the tank—I think he’s referring to the evap system.

    08 Tahoe ltz afm or fuel pump issues???!?

    Sounds like you have fuel and AFM problems. You can disable AFM with a range device, tune, or by physically removing the AFM components, which then requires a tune.

    BCM..TCM..Ground problem..HELP!

    When you added the ground strap, did you clean that grounding point before attaching it? I’d probably check the battery, add another ground from the battery to your alternator grounding point, and try again.

    Cylinder #4 to dreaded random misfire..

    Was it replaced with OE-quality parts or parts store parts?

    Another Tahoe, Another Rough Idle

    It’ll clear up any AFM-related problems and the tune will take care of some other issues (adjust idle, torque management, etc)

    Some encouragement and direction please!

    Yep, what he said.

    Cylinder #4 to dreaded random misfire..

    My guess is AFM lifter collapses or spun in it’s tray

    Another Tahoe, Another Rough Idle

    Also, check your motor mounts. Maybe your engine is idling normally and it’s just transmitting harshness through the chassis
