I have a 2008 Buick Lacrosse CX with the 3.8 liter series 3 v6 engine with 131,XXX. So, this issue first popped up a week ago after coming home from work, which is approximately 25 miles, I really didn't think anything of it. I just thought it was weird because it had never happened before. I pulled into the parking spot at a business and the car just died. All the electrical remained on and but the error message was reduced power followed by starting disabled. So, I waited about a minute and then I was able to start it and go home which was about a mile and half or so. Then this past Saturday I was out running errands and on my last stop which was about 15 miles away from home it did it again while I was sitting in a parking spot for about 5 to 10 minutes. I noticed there was a bit of a rough idle going on and then it just died on me giving me the same errors one after another. I again waited and then turned it back on hoping that it would at least be able to get me home. It started happening more often on my way home and then I just gave up and had it towed to a shop. I have a GPS tracking module on my OBDII port and it was giving me a quick code for the issue but when I tried to go the app that it uses but it disappeared every time I tried to look at it. I caught some of it in the task bar of my phone and it stated something about a module but again I couldn't make out what it was telling me. Any help with this would be appreciated.
Thank you,
Joe Hubbard
Clean the throttle body and MAF sensor. If you've never done so, they are undoubtedly filthy. That would shut down the system.
Thank you for your suggestion. The throttle body has been cleaned recently and the maf sensor has been replaced and relearned. That was about a month ago I believe.
Did you replace the MAF sensor with an OEM one?
Sadly, no. I needed it right then and would've had to order the other.
Have you done any enhanced diagnostics scanning?
I got it at the shop at the moment. I have the blue driver obd2 sensor but the cars system wasn't throwing any codes that would stay on, so I didn't think that what I had would work good enough to catch what it is that's going on with it. When I consulted the shop that I normally go to for my big maintenance jobs they told me that it was difficult to tell at the moment. So that's why I started this thread to see if anyone else has had this issue.
