Clicks on hard acceleration...?
Tried to do a search but nothing.
When I accelerate hard from a standstill/crawl in 1st gear, ~40% of the time I'll hear a metallic/mechanical click from what seems to be underneath the car. Sometimes it's multiple random clicks as you accelerate hard.
It does not seem to be from the engine itself as the engine pulls normally and is smooth as silk. No CELs have been triggered either.
What could possibly be causing this click to happen when I accelerate hard?
Thanks,
FS

I can't tell if it's from the front or rear of the car, unfortunately. I can cruise at speeds >70mph and detect no odd vibrations. I will try to check the joints. Any other ideas?

If you have had any clutch or transmission work done recently the PPF may be clicking from misalignment or improper torquing sequence, or it may be the pressure plate clicking from improper installation.
If you have had the rear wheels off the car recently, the lugnuts may be undertorqued.
Does this noise change depending on whether the engine is fully warm or not? If so, it may be the catalyst making noise as it gets fully hot in a short period of time.

Could it be my U joints on the drive shaft?

It is possible but highly unlikely as u-joints don't tend to audibly "click" when they go bad. When u-joints go bad you will feel a driveline vibration with little/no noise and, since the driveshaft turns 4.44 times as fast as the rear axles, the vibration will be more evident than it would be if it is a problem with the rear axles.

My buddy is a master tech at Mazda, he thinks it is one of my intake manifold tuning valves and not a drivetrain issue. He messed with the valves and said one feels a little gummy--carbon deposits could be making it stick. What do you think?
