There are many threads on this site that explain all aspects of troubleshooting and checking your system. However, the short answer is to obtain a good digital volt ohmmeter that will display %. With your car fully warmed up insert the positive lead into pin 3 in the diagnostics plug located on the driver's side fender close to the firewall and the negative lead in pin 2 or to ground. If all is well your meter should display a fluctuating reading between 40 and 60. If the reading is a constant whole number, your system is not operating in closed loop and the problem needs to be diagnosed and remedied. If the reading is not between 40 and 60 at idle, it can be adjusted with a 3mm long allen wrench at the air mixture controller to obtain a setting of 50. If your meter reads properly, making the mixture richer (turning the screw clockwise) will result in a lower number (I think). My meter reads the opposite but this doesn't really matter since you are aiming for a 50. Once this is set, rev the engine to 2500 rpm and check the reading. It should not vary by more than 10. All that my car needed was to be richened up to correct the hard cold starts, stalling and rough idle. The lambda system can only correct the mixture so much and doesn't correct the mixture when the engine is cold (operating on open loop).

Thanx, I will be able to check this now... :-)
