So I guess I really didn't fix this the first time I just cut off the end and didn't replace the hose. I forgot the fix so while researching it again. I found this youtube video which shows which vacuum hose it is that cracks.
Thanks guys, turned out to be split vacuum line, wish they were all that easy.
Old thread, but which vacuum line was split? I have the same problem after replacing an old intake manifold to a NEW OEM intake manifold... now it's saying valves open and same CEL p1537...
Thinking it's the old IMRC valve I have that on order, but so far I can't see any cracks in any of the two hoses that were on the IMRC valve...arg!
