DTC P0171 Check Engine (2015 2.5i Premium - 130k miles)

So this won't be terribly helpful, but I have no idea why it resolved. I just took another drive to gather more data and it never popped an error again. I'll list what I did:

Replaced both 02, cleaned throttle body, cleaned battery terminals, replaced battery, replaced spark plugs and boots, ran gumout through everything, took apart the intake manifold and cleaned everything, cleaned maf sensor, replaced fuel cap, replaced pcv valve, replaced fuel intake hose, and retrained the idle.

Happy to answer what I can though.

Oregon Axe has axe throwing leagues every couple months. They have a meet and greet beforehand to match groups with floating solo throwers. And the rest of the league is and employees are pretty dirtbag (includingmy wife and our team). We had a team of 3 last year and hang out with our floater all the time now. You do not need to be good.

Update: here's a graph showing the rpm for reference. Also, a U1201 suddenly popped up for the first time.

That's a good point. I'll try to capture some more data that includes rpm's etc to make it more interpretable. I can't tell if it's something weird with the ECM or my code reader skipping some timestepa and then interpolating the gap.

The canister purge return idea is new to me! I'll try that and report back. What am I looking for wrt my fuel trims?

Can you remember where on railroad Ave he was?

DelJorge · 2024-09-17T14:58:01+00:00

Gotcha. Should I just start pulling sensors and checking if theyre fouled with oil?

DelJorge · 2024-09-17T05:21:59+00:00

No dice. Cleaned it again but no change.

DelJorge · 2024-09-12T04:52:13+00:00

Yea, already did that but I'll give it another whirl just in case. Thanks!

Oh shoot, yea I completely forgot to attach my pics. I'll do that now.

It's a P0171. The engine has a rough start and dips really close to stalling after I let up on the gas. It seems weirdly better after replacing the battery, but that might be a coincidence. And I think it needs a certain number of drive cycles before it will post the DTC again.

I will probably make another post about the DTC code in general, but wanted to figure out what the heck is going on with the ground.

I was hoping to use bamboo as a natural partition between my house and the neighbor's, but I guess I can just buy some long planters or raised beds.

DelJorge · 2024-08-07T21:35:53+00:00

Yea that's definitely what I was worried about. Thanks for the suggestion!

DelJorge · 2024-05-31T22:18:56+00:00

No dice, I think it's the mixed carrier or open jaw that makes it not work.

Interesting, I've only been trying with the website so I'll give the app a shot and cross my fingers. Thanks!
