madmarf Posted April 3, 2009 Share Posted April 3, 2009 theres not much difference between the oem and universal ones apart from slight values, and of course, you have to chop your old plug off to put on the universal ones, but a diagram does come with it for the correct wiring. however never use a universal on anything more than a standard car. ony use oem if you have moddified as they might cause u problems then youll be back to square 1 and buy it all again Quote Link to comment Share on other sites More sharing options...
wilkorangerover Posted April 3, 2009 Author Share Posted April 3, 2009 sounds like your fuel pump has been wired to run all the time (not good), check the connectors on the O2 sensor fuel pump wired up to start position , not running all the time , trust me ive just had it out Quote Link to comment Share on other sites More sharing options...
Kev.O Posted April 3, 2009 Share Posted April 3, 2009 its my mates who work in car spares, before buying one... i asked whats the difference between cheap universal o2 sensors and new oem ones, and they said , "not a lot, and the plug" on this supra iam putting money into mapping £7-800 (once i get her running again) , tbh iam not an expert in o2 sensors so next time i wont go messing Sorry to have to be the one to tell you this but it's not just about spending money on the mapping, it's the whole package. Modded cars cost more than standard to run and maintain... fact Quote Link to comment Share on other sites More sharing options...
