I'm experiencing a clicking/ticking noise while driving at a constant speed above 25 MPH (even on highway speed) when I take foot off or push accelerator noise disappears. The noise appears louder and more frequent. I'm also getting a rough idle at times and car is not running too smooth. Can this be the fuel pump inside gas tank? I replaced the high pressure fuel pump two years ago. If you have had a similar issue please provide details.

A bad coil pack will cause rough idle and misfires, usually (but not always) accompanied with a check engine light and latched code.

My 991 has ticking starting cold. It goes away when the car warms up. Never have figured it out. Porsche doesn’t seem too worried either. My car runs perfectly.

Usually starts ticking clicking around 25 MPH and higher speed, cruising same speed or very slowly increasing speed, if I give it a little gas the noise disappears. Doesn't happen all the time but I am starting to hear it more often

Active faults don’t necessarily cause check engine lights. Get a scanner and plug it into the OBDII port. You can borrow one from most auto parts stores.
