Emissions Fail NCT 4 Years, 7 Months ago Karma: 5
So my 1999 MR2 failed today on emissions.
Low idle CO 0.74 should be below 0.50 and high idle CO 0.60 and should be below 0.30

I'm going to put dipitane into it for a week and see if that helps but what else could help??

What i did to mine is get a fuel pressure regulator and reduce the pressure until the car starts to spluttler then just increase it a quarter turn from there and thats it.
You would want to do this around the corner form NCT centre and adjust it back up straight after because your engine will be running lean with low fuel pressure.

Was your engine fully warmed up before going to the test center?

Also check to see if your air filter needs cleaning or replacing.

If you're suffering from lag, you're either in the wrong gear or the wrong car!
