Hi George

This is not what you want to here I am sure. I crawled up my own arse last year on one of these. Emissions were all over the place & vital signals were all within spec (at times).


After many hours of testing, the trader customer presented me with a donor car. Eventually the ECU was swapped & it everything came into line.

At times I had a perfectly switching O2 sensor, which I assumed I meant Stoichiometric gasses were entering the cat, but the emissions were still way off. I have to confess that I did blame the cheap aftermarket cats that the customer had fitted, based on the O2 sensor waveforms. & I had tried a genuine Lambda sensor too, it made no difference.

Great this job innit!

Regards

Dave
