Thanks for the info,
There's no smell like rotten eggs that I've noticed. The previous owner seems to think it may be the O2 sensor. How common is that? What's the cost to reflash the ecu if that's what needs to be done? Also, since my car is under the 8 year/80,000 mile mark, it won't cost anything to get the cats replaced? and if they don't need to be replaced will they charge me a fee for checking it out?
