swabster3000 Posted May 8, 2013 Share Posted May 8, 2013 Hi Guys I need help! I have had an engine management light on now for weeks, Ill start at the beginning, my 350 is decatted, but I have had it for 2 years without any problems, the light appeared out of the blue so I had it diagnosed which came up with - Engine code p0037 h02 htr bank 1. I have been told different things by different people and have tried fitting 'o2 spacers' on the after cat sensors, didn't work, so I had the after cat passenger side o2 sensor replaced as I was told it was that... didn't work. Both times the light is turned out and then comes back on within half an hour but not straight away... I am now totally sick of it and my last resort is to find some cats and have them put back on which will cost me a bomb. Anyone have any other suggestions before I cat my car back together and hope that fixes it...? Quote Link to comment Share on other sites More sharing options...
flyboy Posted May 8, 2013 Share Posted May 8, 2013 I took a spare set of clocks apart recently and there was black tape over the engine check light. Drastic but fixes the light problem Quote Link to comment Share on other sites More sharing options...
