    Wiggle when BRAKING

    I was originally thinking of just replacing nearly everything in the front end as my Tahoe has 195,000 miles on it, but the components are adding up to more than I'm willing to spend right now. I have a Z55 suspension and all parts appear to be original or GM replacements. I'd like to identify...

    Unknown suspension condition

    The GM GENUINE Aluminum lowers are 300+ each. Do I really need to replace the whole arm, can't I press in new bushings and ball joints?

    Unknown suspension condition

    One thing that seems strange, I should have a Z55 suspension according to the sticker in the glove box, but my lower control arms are Aluminum, Aren't Aluminum lowers an indication of Z56 police suspension? As far as I can tell this vehicle was owned by an older couple and no indication...

    Unknown suspension condition

    Thanks Joseph, That part number was helpful. Surprisingly to me, my springs still have the sticker on them and I have the 25783732 part number on my springs, so the springs must be stock.

    Unknown suspension condition

    I'm seeing on Rock Auto, For the control arms i'm seeing both GM GENUINE & ACDelco, Aren't they the same? I'm also seeing adjustable ones vs non adjustable ones. I'm thinking the adjustable ones are for raising or lowering the vehicle? Any good source for the Arnott ones? Saving a few...

    Unknown suspension condition

    Hi All, I have a 2008 4WD Tahoe LTZ with 195,000 miles on it. I bought it 3 or 4 years ago, so most of the history of this vehicle is a mystery. I believe the the relevant RPO Codes are 6H3 7H3 Z55. It's supposed to have air shocks in the back, but the boots are completely gone. The...

    2007 Tahoe sudden P0300 P0154 P0352 P0354 P0356 P0358

    As Bank 1 went completely down, no fire at all. I don't see how I could have melted the honeycomb media. All 4 injectors were no doubt firing saturating it good. I broke down in a bad area, chose to escape rather than wait for a tow truck. I probably drove it 15 miles on 4 cylinders to get...

    2007 Tahoe sudden P0300 P0154 P0352 P0354 P0356 P0358

    It's not quite fixed. It's running fine, but as I was afraid, the money light came on with the dreaded P0420 Catalyst system low efficiency bank 1. I assume the raw fuel hitting the Cat killed it. Any chance this thing will burn itself clean? A new GM cat is over $1,000. Rock auto has some...

    Anyting I can do to prevent AFM issues?

    I got my PCM back from getting the AFM disable done and I've driven it a few days now and no V4 indicated. I don't feel any power difference, but I didn't expect any. I'd highly recommend https://lt1swap.com/afm_delete.htm for AFM disable. Very fast turnaround. Absolutely no side effects or...

    Amzoil opinion

    I use Amsoil in everything and i have since the early 90's I think, I believe in the synthetic products and the Amsoil brand, but this is kind of like religion. You either believe in synthetics or not. I'm actually signed up as a dealer to get a lower price, but I don't sell to anyone. use...

    Is there a PID for Fuel Pressure

    I did find it. The fuel pump is under the live data for the fuel pump control module.

    Anyting I can do to prevent AFM issues?

    That's it for sure, this rocker is right under the vent hole for the PCV, so I pretty sure this rocker is black.

    Anyting I can do to prevent AFM issues?

    I sent my PCM to LT1Swap.com for the AFM disable. While I assume they know what they are doing and will do the job correctly. How do I know if the truck is activating AFM Mode?

    Anyting I can do to prevent AFM issues?

    I'm going to leave the rockers alone. The people telling me this are track racers with tube chassis dedicated race cars running LS3's. They might be pushing their motors a tad bit harder than my wife and I are in the Tahoe;).

    Anyting I can do to prevent AFM issues?

    Two questions, as shown on one of the pictures one of my rockers looks black. Anything to worry about? The other thing I've been told these LS type engines have needle bearings in the rockers that are prone to failure and that it's common to convert to a bushing instead. Is that something...

    What's the new and improved valve cover do? Seems to me as long as it's keeping the oil inside the engine, it's good. Here is a shot of my valley. It sure looks original.

    Anyting I can do to prevent AFM issues?

    The new PCM is in and I did the Crank relearn, no problem. No other errors. I also took off the valve cover. It looks good especially for 190+K miles

    Anyting I can do to prevent AFM issues?

    I recently purchased an Xtool D8 scanner which seems to have the crank sensor learn feature. I'm new to scan tools other than code readers, so it's a learning experience.

    Anyting I can do to prevent AFM issues?

    I got the PCM from Flagship One https://www.fs1inc.com/ they programmed the VIN into it and the factory key worked and it started and ran. I have not attempted to contact them for support as this was not my real issue, but I will. I'll definately pull that valve cover and post some pics...

    Anyting I can do to prevent AFM issues?

    Well I've only had this car a little over 1 year and I have no idea on prior maintenance except that it's in really nice shape which indicates overall care, but no guarentee good oil change maintenance. Many people care for the car, but push oil changes. Oil Consumption is zero or close to it...

    Anyting I can do to prevent AFM issues?

    My 2008 Tahoe 5.3 is running fine now, but i've been reading up on all of the AFM issues. I see the Range Technology AFM Disabler. Most people seem to be buying them for performance or exhaust note reasons, but I was woundering if using this or some other method to disable AFM will make the...

    2007 Tahoe sudden P0300 P0154 P0352 P0354 P0356 P0358

    The ground wire fixed it. I haven't road tested it yet, but it's idling on all 8 with no misfire codes

    2007 Tahoe sudden P0300 P0154 P0352 P0354 P0356 P0358

    99% sure the issue is the wire at ground point G102. Under load the voltage at the coil was 1-2 volts lower than the battery. When I inject ground to the wire I get spark. I cleaned and reinstalled the wire at ground point G102 and the problem got worse. The eyelet connection to the wire...

    The connectors look perfect, contacts are clean, but yet it does feel like the issue is in the connector issue. I'll test under load tomorrow night. Thanks!
