Bad emissions


Recommended Posts

Posted

Hi Guys its me needing help again.

Scoob has just failed its MOT on emissions. CO2 is really high when revved, lower at idle but still a fail. Lamda was also high at first but then dropped down to a pass after some messing.

Before test noticed that one of the hoses to the dump valve was leaking boost under acceleration. This was fixed then reset ECU. This helped a lot but still failed, does it take the ECU some time to settle down? Could the leaking boost pressure make a big difference?

Any other ideas?

Car is a MY96 jap classic, only known mods being apexi dump valve and HKS pipe.

Cheers Ste
