Have Subaru Questions? Ask a Subaru Mechanic and Get Answers ASAP
Hi Im David, thanks for visiting the site. what code do yo have?
thats ok, just ignore the pop ups.
ok, what led you to replace the MAF?
ok, thats fine, but p0171 can be caused by alot of things. before you replace any component you need to make sure its bad by test the voltage, ground and signal to the component. other wise you are just wasting your money.
sorry the first one didnt work, let me try it again
well that didnt work either, dang it
ok, i give up. ill open this up to the others.
when the check engine light went on the first time was that the only code or was there more?
