Smoke smell question. Is this normal?

[pennyracer]

the car runs full fuel when the pedal is to the floor a toyota engineer drove my car and told me when you stomp the pedal the car gives full fuel to motor for max power he called that going out of closed loop meaning the ecu is not controlling the fuel delivery at that time . i have had the same problem on my 08 hb from day one even had the cat replaced by toyota that smell is your cat working very hard to clean the exhast gasses going past it and thats what making your car smell like it does that will in no way cause you any trouble down the road i have 95000 miles on it and still get that smell but not as harsh now also the toyota rep said running premium fuel is a waste of money just buy shell ,mobile, my fav chevron and dump one bottle once a year of techroline in it and you will have no problems with the fuel system at all he also mentioned toyoata builds there cars to run on regular fuel not premium though i still run the good stuff almost all the time and you do see a slight bit of better millage but the extra cost evens out with just buying regular . and do listion to ctscott he knows his stuff and is big plus to this web site
