    M42 hesitation, stubles, falls on its face....

    Bought an car at autcion and it runs just poorly. I pulled intakes and covers and checked the chain, reset timing with cam tools ( it wasn't perfect) And replaced both knock sensors per TIS and the code went away for knock sensor 3-4 but it still runs like poo. idle is ok but if you touch the throttle it stumbles and if you r3v it a few times and let go it falls on its face. Exhaust smells super rich and other than a cam and crank sensor I can't figure what would be causing this. Fuel and ignition timing is off.....
