Scoobymania AFR(LambdaLink) fitted and generally stays on the 9%CO mark, however can read sporadically around the middle of the scale, lighting up on the 3,5,7% lights.
Can happen when car is very hot after good blast on motorway and as tonight just as the car reached running temps.
Could it be the colder weather and how do I compensate?
There is also a worrying vibration which I can feel from my feet on the pedals. Could be a wheel bearing or just the fact my exhaust causes more noise now unresonated centre is on. Will check bearings this week.
Car is MY97, full de-cat, Dawes, itg with reasonator removed.

I get some pedal vibration since I fitted the downpipe, at idle the vibration is in time with the engine/exhaust.
IIRC the standard Lambda sensor becomes fairly inaccurate after a good blast when it gets really hot, I checked mine with a scope once and after a good thrapping the trace was all over the shop.
