    Not much I just got it changed like an over a month ago. And I just drive in town.

    So I finally changed my plugs and wires.

    It is flex fuel. Not sure on fuel trims. I’ll bust the scanner out tomorrow and look and update you guys. I thought it was running lean due to these three things I saw on on the plugs: Some has oil on the threads, some had brick red ash on the tips. And some had white ash on the tips. 8th...

    Used a scan tool. I got one. No codes. Runs fine. Cleaned the sensor, cleaned the throttle body. Not sure what else. I use e85. I doubt injectors but maybe?

    Question about AFM

    I drive a 2014 Tahoe with 175,000 miles on it. It was making a weird rattling noise when it was in V4 mode around 25 miles an hour so I got the plug-in disabler off Amazon and it stopped the noise and it keeps the vehicle and V8 mode so it can’t go into V4 mode to make the noise. Anyway...

    I will add that if you’re not sure about doing Your plugs and wires. Do it. It’s easy. Just do one at a time. I don’t think you can even really mess the firing order up on thess LS engines bc they have individual coil packs. You’d have to really not be paying attention to mess this job up.

    Yea that’s what I was reading. They say to reduce torque 10-15% if using it.

    So I finally changed my plugs and wires.

    I didn’t use any antisieze. Or anything on threads. They came out easy and went in easy. I turned them until they tighten and than one More crank for good measures. I used the dielectric grease on the wires.

    wasn’t having any miss fires or engine light. Ran fine. Runs better now.

    So I finally changed my plugs and wires.

    Right and there’s no telling what the owners before me were running or if they even changed the spark plugs and wires at all. So I guess time will tell. I’ll run it for about 10 or 15 K and then pull one of the plugs and see what’s going on.

    So I finally changed my plugs and wires.

    174k and those are pre gapped. I think they are the same plugs that are in 2010 Camaro. I replaced them with ones for the Tahoe Instead which are also pre gapped from factory. Either .35 or .40mm I believe. I could be wrong

    So I finally changed my plugs and wires.

    Yea seems to be running a lot smoother and even shifting a lot smoother. Idk how to explain but the acceleration feels much smoother and not as rough or uneven if that makes sense. The nice gentleman who was nice enough to show me how to change my plugs and wires says it could just do too high...

    So I finally changed my plugs and wires.

    Bought them last summer and just now getting to them. I have a few questions. It was a pretty easy but I noticed some of the plugs tips were ashy red, some were ashy white and some had oil on the threads. At 175k my dad keeps saying it’s normal for high miles. Need a second opinion. I was gonna...

    Squeaking noise driving me crazy

    Nah something to do with my brakes or something in that area for me.

    Squeaking noise STILL driving me crazy

    Popped wheel off. Seems like rotor turns free for 9/10 of the rotation than it very slightly binds. I don’t hear the squeaking noise really. I hear something

    Squeaking noise driving me crazy

    have no $ till pay day. However, I do have the little pump jack that comes with the Tahoe. Should be enough to lift up the front left end and inspect the brakes and rotor. Gonna do that once I leave the gym.

    I’m guessing stuck caliper, rock lodged between the guard and rotor. Idk. Not a mechanic Just a diy guy if I can
