i recently did a valve adjustment on my 01 ap1 and my check engine light came on, i scanned for the code and got p0411. i double checked all the lines and everything seems to be intact, i reset the ecu and the code popped up again.

i unplugged everything and replugged it back in and the code popped up again

when i did my valve adjustment i did the go, no go method.

my question is, could it be possible that when i did the valve adjustment, the gap on the intake side is too small, and that is causing the check engine light to come on? or should i be checking somewhere else?

anyone?

P0411 has nothing to do with the VA.

check the routing of the vac lines.

Thanks! Yesterday i was inspecting all the plugs and i noticed the pcv valve wasnt rattling when i was shaking it. Its pretty old so ill replace that first and go from there
