25mph: 52/13/64 0.49/0.05/0.02 730/136/1139



the pepboys guy sed it might be my egr... and im thinking maybe i need a tune up or to replace the oil and sparkplugs..cuz i just bought it last last week... also i was gonna try the seafoam...and i dunno but maybe the oil stop leak thickener maybe have made me fail? also maybe i need to upgrade to a better catalyc converter? so whats the best one for emissions and having a nice car but not racing cuz id like to pass smog.... thx maybe u guys could tell me what is wrong from ur past exp....thx

If you throw in an OEM Catalytic Converter, the numbers there will drop dramatically. Put in a new cat before you clean out the EGR ports.
