High Pressure turbo model T5 runs on both petrol and LPG. Flew through previous test with a tester who was the tester from hell. Has done under 1500 miles since then. Put in for test and it failed on emissions. Checked plugs, NGK iridium and can see from soot deposit that the car is running very rich. Although it runs on LPG the moment they boot it in the test it switches to petrol for the extra boost but I noticed a great hesitancy when I drove it like turbo lag and a missfire on booting it. Any ideas?
