car runs like 'poo' with the cap off.. surges and hunts for idle (doesn't sound like it will die, but surges pretty low). I'll have a video in a few minutes.
the AOS recommendation sounds disappointing as I just had it replaced not too long ago. I do have an exhaust leak that I haven't pin-pointed yet though, not sure it they're related.
Is there a way to perform a "vacuum leak" test somehow, or something similar to smoking the exhaust to get a visual of the leak?
after swapping the MAF, no CEL's for 600+ miles.
