Hi Guys
Sorry, not been here for a while thanks to BT, my boys xbox and an unaffordable BT bill.
Thanks for the offers of help but (not wanting to insult you) I wouldn't expect you to do it for nothing, which is all I have at the moment so can't reimberse you.
I just done a bit more testing as there's been some updates from Android Torque. Got some weird scenario's happening :-
Running with MAF unplugged.
3 O2 sensors flipping nicely but bank 2 sensor 2 lags behind and just flips between .1 and .2 volts. Fuel Trim dials show 1x2 and 2x2 unmoving at 92%, Intake temp of -40 degrees C, oil temp -44 degrees C and No injector pulse width reading. Runs closed loop.
Now the confusing bit:-
MAF plugged in....has to be done with car running and up to temp:-
Scenario 1. O2 and fuel trim dials stop working as soon as MAF plugged in, like plugging the MAF in switches them off, fuel trim at 25%. Injector pulse width 71.3ms. Oil temp -22. However...flip the throttle and revs to 1800ish and won't drop until...I turn on the head lights and air con then revs drop!!!!! I cleared the P0100 fault code and the thing runs rough for a while.
Scenario 2. Lights and Air Con off revs to 950, F/T 25%, MAF 3.8gm/second, injector pulse width 71.3ms, oil temp -22
Scenario 3. Lights and Air Con on revs at 750, F/T 16.4, MAF 2.8gm/second, Volume Efficentcy 15.8%, Boost (assume it means vaccum) -12.3%, injector pulse width 71.3ms, oil temp -22.
There seems to be a connection between DB Wire throttle, Plugging the MAF in, turning Air Con and Lights on which will reduce voltage. Can't think why the O2's and Fuel Trim sensors shut down when the MAF gets plugged in unless there's some kind of voltage overload somewhere.
Going to try same scenarios with Omega Spares MAF (ohm performance the same as mine and Steve assures it came of a well running 2.6) and then chinese MAF's (ohm performance the same as each other). I reckon if I get the same thing happening regardless of which MAF is in then it has to be a bad earth or cross wire somewhere.
Phew! Sorry, yet another long post for you to read but I think the devil is in the detail somewhere.
Thanks for reading and understanding.
