Why does my 2003 Ford F150 make a ticking noise when I put my foot on the gas?

What is your question?

It never occurs when I’m idle, it sounds like it’s either coming from the bottom or from the back. Check engine light is not on. But I am due for an oil change in a couple miles, it could be a valve tap, could br an exhaust leak, I’m not entirely sure

What makes this problem better or worse?

It comes and goes, worse when it’s hot

How long has your 2003 Ford F-150 had this problem?

A month
