P0171: System too lean (bank1) Fix (Stuttering between 3-4k RPM Full throttle
Hello guys
Yesterday my check-engine-light went on and I instantly noticed a stutter between 3-4k RPM at full throttle. First I thought it was misfiring but I wanted to check the error code from the ECU.
My lancer threw the error code P0171. This was due to an fuel pressure hose that isnt fixed properly.
On this picture you can see the pin where the hose should be.
If you are experiencing this problem with this code check this. If its allright fix it with a zip-tie or get a new hose that fits thighter.
If you ignore this error you will lose power and eventually melt your piston.
