i got code po171 and it has a high idle but its even at 900 and the truck runs great. other thatn ****ty mileage and a manifold leaak

 

If you fix the manifold leak the 171 code should go away unless you have a hose also leaking. Your fuel mileage will come up also. This is something I wouldn't put off. If not, then you will still be paying more at the pumps.

 

ok well i ordered pacesetter longtube headers so they will get here soon and will drive the ranger for now. i will post update soon maybe
