So I took the car to a mechanic who replaced a bad hose on the intake manifold (I replaced them all so idk?)

and the car was running pretty good...but power was GONE. It was the slowest that I have ever felt it...

So I basically was trying to figure out why the hell all the power was gone by a simple hose being replaced.....then I realized that about 6months ago I gave a tweak to the EHA valve so see if lower chamber pressure was an issue, so I unplugged her, turned it back to the stock position and I got the power back
....but at the cost of the misfire. The misfire got worse back to where it was before.


Can this give any indication to anything??

I am taking the car to a shop with a leak detection smoke machine next week as I just found a shop that has one locally so I say with absolute certainty that I have no vacuum leaks left.
