thorne Posted March 30, 2006 Report Share Posted March 30, 2006 After my dyno run I've had some problems ( UNRELATED TO ANYTHING BRIAN DID) I put some Octane booster in with my 94 octane the octane booster is called Turbo 108. Now I got a CEL code P0420 Catalyst System below threshold bank 1 AND my temp gauge just stopped working reads nothing suggestions help anything .

el aguila Posted March 30, 2006 Report Share Posted March 30, 2006 Sounds like a downstream O2 sensor isn't working properly, or the catalytic converter is defective. Quote Link to comment Share on other sites More sharing options...

Guest 78novaman Posted March 31, 2006 Report Share Posted March 31, 2006 Empty tank of all gas. Fill up all the way with the recommended octane fuel. Put-put around the block. Reset computer. Should be good to go Quote Link to comment Share on other sites More sharing options...
