Hello all, I have recently gotten the 0171 code again, the last time it was both of them 0171 and 0174 along with some egr codes. That one turned out to be the vacuum control solenoid that controls the vacuum to the egr valve. Been driving it well over a year now with no more problems. Now the cel has come back on a couple of times with just the 0171 code. Just for kicks I tried purchasing my gas elsewhere that doesn't put ethanol in the gas. It's been fine the last couple of months, no cel. My wife just put gas in from wal-mart the other day, now I have the 0171 code again. I am wondering if this is just a coincidence or something more maybe.
