well, not sure its related, but I just reinstalled my entire exhaust system because of smoke and smell of fuel. Now that its back on..no smoke, no smell.. BUT..as someone said in another post..I have a very finiky LLY for some reason.

My 2004 I put it back on. Terrible noise at a stop, in gear. 2005 cat off no noise. I don't know if it was because of different exhaust systems. I think it was.
