Okay, so I bottomed out on a bump a couple of days ago and ever since my car has been acting funny. Every time I hit a bump my car bogs suddenly for half a second, or if there is a consecutive amount of bumps it starts bogging pretty bad. It also smells like its running a little rich.

I looked under the car and found that my 02 sensor (cat) had came loose and was barely threaded on. The 02 sensor looks fine, so I tightened it up, but it still continues to bog on bumps.
Is this usually a sign of a bad 02 sensor. Should I buy another sensor or is there anything else I should take a look at.

PS. I throw no codes and I have a test pipe with the 02 sensor fix if it matters.



Thanks.
