P0171& P0174

[Shane Dinsmore]

I put my stock air intake back on the other day and didnt plug the vacuum hose in good so I am driving down the road and it pops out. I pulled over and put it back in (good this time) and the CEL was on. I had the codes pulled and it is the 0171 & 0174. I checked the notorius elbow just to be safe and it seems fine. Do you think the vacuum hose would have thrown those codes and I just need to clear the CEL? Thanks.

I would tend to think so , Unless you also did not clamp the intake clamps on good enough also..

I am with Todd.



Either way you would have leaned out the the fuel mixture. Same end result, just a different cause by location.
