Alright.....after the constant nightmare of trying to make a lemon into something great again, i find myself running into another headache

After changing the engine due to bad piston rings, and a chip out of one of the pistons....

I find myself one last (hopefully) problem...

I've got a miss, only, when the gas pedal is pushed down more than halfway and normally happens between 2000 and 3500 RPM. It only does this while driving, because i can sit idle and rev to red line and it doesn't miss at all. I can hear the turbo run and spool up nicely, then it starts to miss for a few seconds then it sounds like the turbo stops spooling and the problem goes away, and get crappy acceleration after that.....but then i change gear and have the same "pin you to your seat" acceleration until i hit that miss again.

Not plugs or coils.....those are brand new....I'm thinking since it was burning oil for such a time (my inside of my exhaust pipes are stained black). that my Cat is plugged. I recently had to replace the Gasket between my Turbo and Exhaust manifold....I'm thinking this could be the back pressure from the plug in my cat?

You need to get it scanned for faults that will give you an idea where you fault might lay

Multiple Misfires....and the cylinder misfiring changes i tested it, it was cylinder 3.....the mechanic i go to tested it, and said it was cylinder 4. i tested it several weeks ago and it said Cylinder 1

To make a start check your coil pack wiring harness for cracks etc.

Wiring harness, compression test or turbo inspection.
