CO Min.2000 RPM > 0% - Its ok now
BUT
Lambda sond > betwen 1.06 and +/- 1.15 - Emission test failed again
I think is one thing its strange
When the throttle is on 4.000RPM and the car stoped the engine goes up and down. +/- 500RPM up and +/- 500RPM down. Its normal?
HELP ME PLEASE
That is normal
That is a engine speed limiter that kicks in, at 4000 RPM, only when you are in neutral or park
