I noticed the tick tick tick had gone from the red flashy light until I earthed out the STS module. I cleaned the mount bolt holes and refitted the unit. I then scanned the unit and 2 faults as per usual listed. I did a quick erase and hey presto they were gone! I did it 3 times and even sat in the passenger seat bouncing up and down, the light stayed OFF!
Now comes the tecky question about the emissions. I'm none to good on petrols
On "Live" data I see that the Oxygen sensor output voltage on Bank 1 Sender 1 is ranging from 0.260 - 1.275V where as Bank 1 Sensor 2 is a steady 1.275V. Is this the cause of my fluctuating CO and Lambda emissions?
Now I haven't cleaned the MAF. Would it be a contributory factor?
Any guidance helpful. I will repost this on the "Electrics" thread too.

What engine is yours? As I do have a known good MAF on the 52 reg 2.0 non turbo petrol which will be going to car heaven soon, which you're welcome to for the cost of postage.
