Problems Again!!!!!

[jjs_82]

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.
