no cats. thats your problem... mine is box stock and I get a whiff of rich in the morning when its cold.
the engine is running in open(or is it closed loop when cold, can't remember) and this means that the computer is using pre-determined tables to computer mixture... and they will run a bit rich.

You're BLM seem pretty decent. Ideal is 128 but I understand if your +/- 8 you're ok. A BLM under 128 would say your running rich, over 128 says you're lean.
