Bad misfiring an hesitates when warm

[jezvalva]

I was happy with just unplugging the map sensor an having a higher idle than normal but it was only a quick fix, now after looking harder an changing loads of parts an nothing would get rid of the bags of misfiring when I flatted the throttle, until I disconnected the lambda sensors an it would run perfectly, no hesitation.

My problem is that Ihave already changed that sensor to a NTK sensor I bought from my local factors £76 .
I took it out an changed it back to my old sensor an i ran a little better, but still hesitates.

I did clean the sensor first, now it's still running rough but I don't get a fault code.

And what does the live data seem to say?

 

[jezvalva]

Il admit Ihave n't been taught how to read much less understand it.

But the reading went from 600-0 on mere tick over
Never a constant like from the rear sensor 450.

That's correct then, the U/S sensor should switch from rich to lean where the D/S should remain stable. And the MAP value?

 

[jezvalva]

I don't recall off hand. I will let you no tomorrow.

So if you had a fault an only unplugging the lambda sensors made the car right what else could that suggest?

Does anyone no if the two o2 sensors share a ground wire? But not the signal yeah?
