2000 Land Cruiser. Shouldn't be too much slack, but I haven't touched it in a few years so I'll double check. Don't have multiple/thick floor mats either. The code I was clearing was a P1126, which will randomly pop up and disappear over the years. Everything I found on this code showed people replacing the throttle body assembly (only sold as a complete unit). Now I'm wondering if it's related, but I don't know what the normal range for the engine load is. I would assume it's at or near 100% at WOT, but wanted to verify.
