jjs_82 Posted October 3, 2011 Share Posted October 3, 2011 Hi all, Having more problems this time emissions!! [ANGRY][/ANGRY] Have had 3 NCTs and failed everytime on emissions, I thought it was a boost leak so i changed all the vacuum pipes and put i also put in new exhaust gaskets, so i def have no leaks anywhere and it's still no good. So today i went and got an emissions test done and it's very high on low idle and high rev so i unplugged the lambda sensor and my emissions comes down alot but still not enough so tested the signal on the wires going to the lambda and 2 wires read 0.0v (volts) and 1 reads 14.2v and the other is 0.1v so am i right the signal wire from lambda to ecu should be between 0.5 and 0.7?? but im not getting this!! What could be wrong?? Thanks. Quote Link to comment Share on other sites More sharing options...
