    Help: 2007 PPV Rear Differential Spider Gear Kit & Clutch Plate Set

    If you had a clunk when pressing the accelerator after coasting did this by any chance fix that?? Sent from my iPhone using Tapatalk

    Intermittent rough idle

    Still no fix on mine. Turns out the air thing was not the issue. Figured I’d take it to dealer due to it still being under powertrain warranty. Took it in for the random rough idle and the trans shift/clunk on accelerating after coasting. Their specialist/head tech said he felt both and...

    Intermittent rough idle

    Same here Holidays and been on vacation. Only thing I found was that I may have possible air being pushed through the fuel lines somehow. Other than that people tell me I’m crazy and that chevys run like that. Hell no. If I could fix the idle and that stupid clunk it would be a...

    I keep doing the same thing with the logs. My trims are more on one side as well. Sent from my iPhone using Tapatalk

    Those numbers look way better/ more stable than mine. Was that test before or after the b-12? Glad to see you’ve got it back to normal without the tune. Must mean you’re on the right track. Sent from my iPhone using Tapatalk

    Hope you don’t put your issue. I know how annoying the little things are. If you already have the sensors might as well put them in. Doesn’t the system go into open loop st full throttle runs? Wouldnt that take the sensors out of the equation... ?

    Upstream vs Downstream O2 Sensors

    I haven’t checked after the e85 as I’m on the road with the fam. It still stumbles but is greatly reduced. When purging the gas it felt slightly warm. I put almost a full tank of 93 in and it’s just like before. I also loaded the BBP tune in to see if that would change it but did not...

    Upstream vs Downstream O2 Sensors

    Yup. We will be there today. Leaving Biloxi in a few hrs. Gotta change the wife’s BMW X5D thermostat and pulleys when I get there also. The Tahoe is pretty reliable but it’s the small things. I’m curious as to what the OP trims look like at idle I can post mine as well. I’m not...

    Upstream vs Downstream O2 Sensors

    we are going to Pensacola beach. I stay on the west side of Houston. I will probably do the fuel pump even though the wife says no [emoji48] hehe. It’s one of those things I have to figure out. I will definitely post back when it gets done weather it helps or not Sent from my...

    Upstream vs Downstream O2 Sensors

    It was a fuel gauge kit from oriely. And the idle is terrible. On the gauge video i was resting my hand in the car and the vid is shaking. The scan tool has it going from about 40-45psi just not as erratic. Not sure where the pressure gauge is getting the reading from as the analog gauge...

    I was thinking the line inside the tank that pushed the fuel up. Or possibly an irony somewhere. Sent from my iPhone using Tapatalk

    Upstream vs Downstream O2 Sensors

    I have the same “misfire/stumble”. Everyone tells me it’s normal. I can’t stand it. I did check my timing with blue driver and it bounces around while all my other cars are steady. Driving me nuts. Have you found any solution?? FYI here’s my data at 2500rpm no load Sent from my iPhone...

    Intermittent rough idle

    Any luck fixing your idle??? 2014 PPV 57xxx. I have the exact same issue tried checking everything for leaks and cleaning the MAF and TB no codes and idle sucks bad. Ran injector cleaner etc. still bad. All I have right now is blue driver scan tool. A Buddy told me to get the new GM MDI...
