I have a cel on after changing out an oil seperator line. Once the car is warm its seems to only be exhausting the the left exhaust. I am thinking its a catalyct convertor. The car vibrates quite bad under 2800rpm once at operating temp. What concerns me is that I am also getting a cylinder 6 misfire and there seems to be a loss of compression on the cylinder as well after completing a dry/wet compression test. It looks as the the coils are find, but the couple of times that the car has been in the rain for too long it seems to idle/run rough. Any thoughts on this, because the bills on this car are really starting to add up and is starting to make this car an unejoyable experience. Thanks in advance for any advise!

If compression is low, perform a leak down test. This will pinpoint the area of the loss. - Nick
