P0171 Code in an EP3, Its feeling really sugglish

[DarkCreep]

People seem to say its the o2 sensor but I highly doubt it with this.

I scanned it and got that one code and it says system is running too lean. It feels really sluggish, takes forever to start, and is just slow.

Would replacing the fuel pump fix this??? :thumbsup:

Any other codes?

Check the fuel filter, fuel pump, FPR, and EVAP canister purge valve. Basically start by measuring the fuel pressure.

How do I check the FP?? I tried hearing it prime like I did in my EK and I dont hear the same noise.

and thats the only code btw.

Measure the fuel pressure.

Are FPRs expensive?? Ill tell him to purchase the filter first, although I really think its a faulty fuel pump because it was fine when he bought it, then 2 weeks later it died.
