lower performance when check lengine light is on?
my car is putting out code "P0420" Catalyst System Efficiency Below Threshold (Bank 1) , now i tried resetting it but it goes back on after 20 miles... I dont have any cats so im not worried, but is the car actually slower now that its in "limp" mode? I do have the cel fix but it doesnt seem to stop it... any ideas? is fuel economy affected as well?

Just to give you a heads up Kayo i ran my fastest times at the track when i had my cel on P0420 and my front O2 sensor wires striped. hhah 13.6 in the 1/4 is damn fast in hawaii Pretty much a stg 2 w/o utec. That code you have should not put you in linp mode its all in you head bro.

I haven't gotten it checked yet. I don't want to just reset it because it might be due to the incident
