• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Flaky TPS 07 GXP

    On my way to work, I get a TPS light. If I look at the actual tire pressures, the LF show 3 dashes. By the time I get to work it is off and the tire pressure is showing an actual value. Is there any diagrams on TPS? Off the top of my head, guessing, there is just one receiver. That tell me that...

    Oil leak GXP, thought it was main, but maybe not

    I was hoping for a second set of eyes. The last 30,000 miles I have had to add some oil and the oil pan is wet. All of this started when I replaced the valve cover gaskets. I wonder if that started holding the blow by more? The car has about 190,000+ miles. When I pull the torque converter...

    Headlight adjustment screw issues. (07 Grand Prix GXP)

    I got some new headlights and was trying to adjust the driver side. As I was turning the adjustment screw it was not moving and then the mechanisms jumped out of the socket. At least it looks like a socket with three tabs. I am working on getting it warranty, but I curious about how the...

    Help identifying and sourcing 07 GXP trim that is below driver rear door.

    I had a road construction incident that almost knocked off my driver side, rear door, lower trim. It was being held on with the rubber seal and back screw. It was knocked off all the white clips. After pulling it off, other than some missing part on the very bottom, it does not look too bad. You...

    Really impress with todays off the shelf oil detergents

    I started new thread since it was not related to my plug question. As I mentioned before 172,000 and replace the plugs, wires, and valve cover gaskets. There was zero varnish. Here is a close up. I am not sure what the small brown clump is. This picture is really zoomed in. I don't think it is...

    Reading Plugs 07 GXP 172,000+

    So I was at 172,000 plus miles and thought I would replace plugs, wires, valve cover gaskets. I did not feel a plug/wire breaking down just thought of it more as prevented maintenance. The plugs looks a lot better than I thought they would. So 2, 3, and 8 was really carbon fouled. 4, 7, and 6...

    Any tips on replacing valve cover gaskets?

    This Saturday I am doing plugs, wires, and valve cover gaskets. I done lot's of 3.8 but this is my first LS4. I assume the trick of rocking the motor works. I did a search and found this guy doing an Impala. How to Change Valve Cover Gasket Chevy Impala 2006-2016 - YouTube Looks like there not...

    Android Auto Issues

    Just installed a Pioneer NEX2330 late December 2018. My Android Auto (AA) has worked with no issues since then. I am not an audio expert by any means. My GS8+ android OS update dated a few days ago (Feb 3rd) and since then the head unit will not pull up AA. I just was curious if anyone else...

    GXP whining sound, that comes and goes, does not stop the second the engine does.

    This is going to sound crazy. About a month ago my wife was driving the GXP. She stopped at Walmart, did her shopping, and started the car and heard a noise. Called me, I was afraid a belt idler or tension bearing was going out. I drove there had her start the car and all sounded good. So we...

    Pontiac Indian Head Service Clocks

    I did a quick search of this forum for "pontiac indian head clocks" and came up empty. I am curious if anyone on the forum knows anything. Googling the internet there are a lot of reproduction that seem expensive. Found some on ebay for little less than $50. What about originals? How to tell...

    Raspberry Pi - Virtual Sensors for Car Computers

    I am changing the name of the thread to fit the direction it is going. In earlier models there is no CAN-BUS, looks like maybe around 05 for our cars. So really it looks like I need to better understand the systems. To acomplish this by creating a function system of PCM/BCM and emulating the...

    97 DIC Only Fits 97's But can you ....

    Not sure if this is a "General Tech Discussion" or "Audio, Security & Visual Electronic" so, I guess here first :-) Every post I have read said only use 97 in 97. Seems that 97 has a low tire pressure light. Looking at all the instructions I don't see a difference in how to wire them, other...

    What are these attach to the wire loom for Digital DIC (98 GP)

    I was looking to replace my analog DIC with a Digital. I have read the threads on this and other forums. I seen the hack to get a NON-97 digital DIC to work on a 97. My question is what are these parts ('Yellow' #1 and 'Blue' #2) attached to the wire loom. When I pulled it from the donor, I cut...

    Mode $06

    I searched the forum and did not see anything on it. I have done a lot of internet searching on the subject. From what I have found so far, seems to vary not only from manufacture but by model. Here is the web site on it for GM. http://service.gm.com/gmspo/mode6/index.html I am using the Torque...
