The ligier Ambra has a 505 engine that has had its emissions measured, I think!
you could alway get it measured at the mot station…

Most of the engines now-a-days use Electronic Fuel Injection (EFI) system for better combustion, fuel economy and emission control. But old carburetors are still there in some engines.

the engine light is on and it doesn’tt blow any smoke at all
No, it is a big read light to the emission people that something is wrong. Some states like Washington don’t even test the emissions on later model cars with OBD 2 systems. The explanation is their test equipment is no better at checking [...]

The statement from the emissions facility is: (code) P0442 evaporative emission control system leak detected (small leak). Is this expensive to repair? It’s a 2001 Chevy Cavalier.
The code is typed word for word above - they did not provide me any additional information at the testing facility other than to say I should take it [...]

Independent tests conducted by engineers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory on the mono-fueled version of the BMW Hydrogen 7 prototype have found that the car’s hydrogen-powered engine surpasses the super-ultra low-emission vehicle (SULEV) level, the most stringent emissions performance standard to date. For more information, and to see a higher [...]

My check engine light has just come on, I have a 2003 Ford Taurus. A friend tested it with a diagnotics and it says I have a low level leak around the gas cap. Can I bypass this somehow to pass my emissions test till after vacation.
here is how the test is preformed
first check [...]
