Even  with cool weather, 93 octane doesn't cut it now. Use 
94, and I'm fine.  Havn't changed anything and plugs have 
5k miles on them. Any  ideas?



Where do you live?
Colorado just started using oxygenated fuel year round, and it messed with  
my vapor lock problem, and made it a year round issue now as well.
They could have messed with the fuel, even though the octane rating is the  
same.
