engine issues

Jolly a couple of people have used this company for rebuilts. https://www.barnettesengines.com/Home_Page.php
They are closer to you also, they are close to where I am so was looking at using them at one point.

Any resolution to this issue yet? I'm getting a cylinder three mis-fire code, usually during extended idles, but I have gotten it during acceleration sometimes. I've done the coil pack switch (code remained with cylinder three), and installed new spark plug (code remained). I also seem to have a loss of power, but also have a pretty rough idle. If I listen to the exhaust it sounds like it's missing, but the engine sounds like it always has. Haven't done a compression test yet, and from the research that I have done the possible issues that I have found have been:

-faulty spark plug
-faulty coil pack
-faulty oxygen sensor
-faulty fuel injector
-burned exhaust valve
-faulty catalytic converter
-running out of fuel
-poor compression
-defective computer

Also reading around on the forum it may be due to a bad intake manifold gasket and/or bad IAC.

I really need to narrow this down, so any info from your experience would be helpful.

In my case we found two burnt exhaust valves on cylinder #6. Appears to have been caused by (thermal damage/possibly mouse chewing) to the injector wire/connector harness to #6 injector as it wasn't pulsing/spraying fuel as it should (lean condition) until my mechanic replaced the end wiring & connector harness.

On the bright side my engine looks completely devoid of gunk or sludge and looks new inside. My mechanic has checked out the bottom end and doesn't feel that new bearings are necessary. He has replaced the rings and honed the cylinder walls and was surprised at how little taper there was in the cylinder walls...maybe half a thousandths. He put the engine back together and his assistant is installing it back in my VX...should get her back anytime now.
