Has anyone experienced a PO171 code with a Volant? This is the second time the CEL has tripped and I've pulled this code in a couple of months. I've only got 10k miles on this truck. Never once had this issue with my '08 X with the exact same intake. Checked that all the hose clamps are tight on the intake tube connectors, and the MAF sensor opening is sealed. Any ideas? I honestly don't know if the intake is the issue, or if I may have an injector problem or something along those lines. Just seems odd that it's only on one cylinder bank. I suppose it could be a malfunctioning O₂ sensor. I guess if I get it again, I won't clear the code before I put the stock intake back in and take to the dealer. Unless anyone has any other advice.
