I've had this issue, too. Basically, check for exhaust leaks and proper
oxygen sensor operation. Most likely, you'll need to replace the manifold
and catalytic converter assembly. If you're lucky, recall V04 will still
be open and your manifold is cracked. That'll get you a free replacement.
(You should also get a free replacement if you're within the 8 year/80k
