Re: cat

["John Darwak" <jpdarwak@flash.net>]

You don't say if you tried changing fuels. If you did, did it make any 
difference at all?

My car does not like Mobil fuel. It gives off a weird smell (no I won't try
to describe it). Switching to Schell or Amoco works fine.

I would think that removing the cat would trip the second O2 sensor for sure
and would probably cause performance problems as the computer would try to
compensate.

The Service Advisor's comments about "slow burning fuel" only suggests to me
the sad state of education in todays schools...

You might try posing this smell question to the VR6 list.
