It's it knocking or ticking? If it's knocking it could be a couple of things, rod bearing or wrist pin. If it's ticking it could be several things-cheap gas,cam,lifters,valves,optispark. Hope this helps,when you get it fixed let use know what was wrong.

It sounds like spark knock (ping) as it seems to be affected by load. The thing is to find out why. Is the SES lite on? Make sure the knock sensor is good an screwed on tight, make sure the knock sensor module is good. Also, has someone messed with the computer? You should be using premium fuel, this engine was designrd for it.
