From the research i've done into my high HC count, it looks like its going to come down to either a bad catalytic converter or a fault O2 sensor. I also happened to catch an episode of Motoring 2002 on TSN and garage guy said cars running too rich/lean .. check the O2 sensors.

So my next question is, how many O2 sensors are there (as the guy on tv said some cars have several) and much should i expect to pay? How much does a catalytic converter go for? And just how long are these componants supposed to last?

My cars goes back to the shop tomr for the diagnostic...

thanks for the replies!
