hello again,
i dont own a smoke tester and im still to get the emmisions tested but here are my scope results,

1) is of the MAF Sensor upon reving.


2) TPS KOEO


3) TPS KOER


4) HO2 Sensor at idle


5) HO2 Sensor when reved.

The HO2 sensor that i scoped is the 3rd one that has the normal 4 wires the to nearer the manifold have 6 wires and cnat get a decent reading from them. but when its been reved it goes to around 0.6-0.7v and just stays there for ages untill then slowly drops down again.

Im inclined to say the sensors buggerd but dont want to order expensive parts if there not needed.

Thanks for looking any help would be great,

regards mike
