what would cause a car to sputter and have no acceleration/power.

What is your question?

here's everything I can eliminate right off the back: Spark plugs, spark plug wires, oil, solenoid, bank2 sensor2 02 sensor, spark plugs, and ignition coils. The check engine was on before I changed all of this and is now off, but still absolutely no difference in performance. it turns on good, when I put it in drive and hit the gas it barely moves until I push it all the way down. theres slight knocking in the engine but it comes and goes, I tested the pressure also and its good, so the engine still has power. what would it be!!?
