Hello!
Sorry if this is the wrong topic.

Last night I swapped out my spark plugs (Ik22s), intake manifold (GE8), and throttle body (R18). The car drove fine for the hour commute to work, but popped a P145C code the second I went to leave. The code says EVAP system purge flow malfunction.
I’m wondering if anyone has dealt with this before.

There are two things I’m thinking I did that could be causing. First is that I didn’t adjust a set screw on the throttle body to limit the air flow. Second, the intake manifold sensor came out kind of rough from the original intake manifold. I didn’t think I damaged it but am wondering if that’s maybe a cause.

Thanks for any tips!

EVAP line looks fine. I think I figured it out. I think it’s the canister purge valve. The R18 throttle body didn’t have the same mounts as the CRZ so the purge valve is just kind of hanging. Plus I only have one hose connecting to it (don’t know where the other smaller connection is supposed to go). Hoping I can find where that goes and have it be all good
