Hi guys. Took my car for its MOT yesterday, it failed on minor things likes bulbs and wipers etc. But the big thing was the exhaust emmisions were WAY over. I know there is an adjusting screw on the ECU but my question is 'which way do you turn it to turn it down clockwise or anticlockwise?' The car is a near standard 1990 G 2 wheel drive, only engine mod's are stage 1 chip and air filter eliment.
Thanks in advance for your help.
