RallyeCAV606 · 01-28-2008, 12:01 PM

I have a 92 Audi 100 2.0E with AAD engine. When it start and after some time when i meseare the co looks fine but after a while and especially when I drive one round of the block the CO go streight up to 10 and HC to almost 1000. I change the water temperature sensor the oxygen sensor and the pressure regulator with new. I also change the ECU with used and I mesaure all the sensor which everything seems ok. Is there anything else that i can check?

You might hv to check the compression of each cylinder,1 st pull out the ingintion coil output spark plug cable to distributor cap. 2 open up one by one spark plug and insert compression tester kit. or O2 sensor output voltage in the range of 0.2 to 0.8v
