So I ended up changing my ECT sensor on my trailblazer 06, which was a complete pain in my ***! Temperature gauge on my dash is finally reading accurately, but the code is still up so i think the thermostat might be gone as well? I don't know I don't want to get into it now because I have a bigger problem. Hopefully I'm posting in the right forum!
So I'm running a code p0171 "system too lean bank 1." Does that mean I'm getting to much oxygen or not enough, or to much or not enough fuel in the engine? This is a '06 trailblazer that I bought about 6 months back. A lot of problems that I've been having to fix. Vehicle came from Maine, which is rough terrain up there and cold winters, and I bet whoever had the vehicle probably beat on it a little and took it off roading. It has about 126xxx miles on it! I've already fixed so many codes, and problems I lost count! I think its because its a old vehicle with a lot of miles and it came from the state of Maine..bad winters..
The tb is surging when I start it up, almost sounds like its going to stall about every 2 or 3 seconds, and then picks right back up. When I'm driving, it performs horrible, horrible acceleration. I cant really notice the surge when i'm driving , but i can hear it when the car is idling. I also have an exhaust leak, I don't know if that's triggering the code, but i doubt it because exhaust leaks are emissions. I think the leak is in the manifold gaskets. That's for another day though. I know this p0171 code is "broad" and can mean many things, it's hard to track it down, so I was seeing if someone could help or give me some advice from the information I have provided.
Thanks!
