P0430 GM Error code Help...
I all, I have a 99 Camaro with the LS1 and yesterday my service light came on and gave a error code of P0430: Catalyst System Efficiency Below Threshold (Bank 2). Anyone know what the hell that is?
Also,.. I have always filled my car with premium gas and the last 3 gas fills I have also used this stuff called STP Octane Booster:
http://www.stp.com/fuel_octane.html
Would this cause this error?
How can I fix this problem?...
