My car is smoking
After heading up a somewhat steep hill (2WD/rear locker/tires sliping somewhat) that is a little longer (takes about two minutes to get up) my car starts smoking. It does ok on hills that are steeper and shorter, but when I get to the top of the hill discribed, smoke comes rolling out when I open the hood. I have actually tracked the problem to the CAT. Is it clogged? My weber still runs a little rich (which I know increases as you head up a hill), which could be the problem, but still that is a lot of smoke for a two minute climb. Any experiences, advice? Thanks guys for all the help so far.
