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.

YouTube - Ford Ranger IMRC

 

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!
