SO changed the plugs, 8 now cops, cleaned the mass air, new fuel filter..... and yet it now runs like a 3 legged dog. has absolutely no pick up at all. not only that but it seems like it bogs down before upshifting... any ideas?

 

Any codes?

Check and double check all the connections, Could be the MAF isn't plugged in all the way. You didn't touch the little wires did you?

 

How did it run before you did all that?

 

+1 could even try a battery disconnect and reconnect

 

It had a pretty bad miss, I was using an edge before. I'll try disconnecting the battery for a bit to see if that resets some stuff. Also I forgot to mention I'm starting to get some minor cam phaser noise I think. I'm sure that kills power when those dont work right.

 

If you have an Edge, return the tune to stock.

 

I did haven't used it for about 3000 miles.
