Have a ticking or knocking noise in engine that gets louder if you press on gas.Scaredtodrive

What is your question?

Problem started a few weeks ago. Car did not want to start. Then a tapping sound started and lost power a few times. Check engine lite came on and we quite driving. Upon starting the noise starts and gets louder if you give it gas. Have changed battery, starter, plugs,oil and still no better. What could it be.

What makes this problem better or worse?

The sound starts after cranking and gets louder if you press on gas
