re: OBD2 scanners

It is intermittent, but consistent if that makes sense. I have done everything that I can think of to alleviate it, but nothing so far has worked. Put it this way, I've done everything that a full 100k tune-up would do and then some. It is enough to where it would take me 10 minutes to think of it all, and I'd still forget some.

What info are you looking for, specifically?

A clue

I am figuring that a live scanner will be able to show me something so I'm not just randomly take things apart or throwing money around. Possibly a bad injector or coil pack that aren't bad or consistent enough to get a code


Only thing that I know for sure is wrong with it is two snapped off exhaust manifold studs and a broken fin inside the muffler. One on the front passenger side and the other on the driver rear. Copper gasket maker around the ports and they are "somewhat" sealed off. Did it before the exhaust manifold swap, and has gradually gotten worse. New o2 sensors and cats are both good

Problem feels internal
