I am getting a P1071 and P0174 code on occasion, it goes away after a few starts and then will pop back up again a month or two later. From reading I have gathered that this means that is on the intake side as I am getting both simultaneously. I have already re-tightened the stock intake twice. (I have a Svede to install but I was waiting to try to get this sorted out first) I believe the next place to look is the intake manifold. I tried spraying around the edges to see if I could get an idle change but nothing happened. Is my best bet to re-torque the manifold? I has to be a pretty minor leak I think but my logic could be completely wrong.
Your thoughts please!
Thanks in advance,
John
