first off, Hi everybody~
i installed the UR intake and Forge type RS recirculating valve for 2 weeks
and the engine light came on today the code is P0171 - fuel trim too lean!
anyone know is the intake or the valve causing the problem?

any help would be appreaciated~

 

Are you tuned?

 

no~

 

read ttp engineerings post about the UR intake on the 09 ralliart without a tune. its making your car run dangerously lean...its here somewhere.

Good work people.

 

does that mean i should get a tune? or replace the intake?

 

Either will fix it. From a performance standpoint, getting a tune and keeping the intake would be the ideal solution.

 

Knowledge is power, Do your homework first.

Get a tune asap.

 

ur lucky that check engine light is all u got...

 

lean = DEAD MOTOR go get a tune asap

 

i think i will take it off before i get a tune~
it s hard to find a good tunning shop here in toronto~
