oil cleaned up,
every connector in the vacinity cleaned with electrical cleaner,
maf cleaned, throttle body and intake cleaned,
new bosch plugs and coils fitted.

fault codes,

p1340 - camshaft position with respect to crankshaft bank 1 below limit value
p1341 - camshaft adjustment bank 1 exceeds limit value
p0150 - o2 sensor ahead of catalytic converter bank 2 signal implausable,
p0130 - 02 sensor ahead of catalytic converter bank 1 signal implausable,
p1126 - oxygen sensing adaption lower load range bank 1 exceeds limit value,

so cleaned cat electrical connections again today, not much difference.
looking at the codes all is bank 1 except the other o2 sensor, if the o2 sensors were the cause then i would expect to see the same codes also for bank 2?
so im thinking bank 1 cam solenoid? or is it possible to have jumped a link on just bank 1?

it starts fine but idles lumpy, its lumpy if i use too much throttle untill about 3k revs, worse uphill, would this hapen if bank 1 cam solenoid stuck in the position it would be in if the car was under heavy acceleration?

could the o2 sensors just be dead because its been burning oil due to the aos? can i swap them with the ones after the cat to see if fault follows them or are they a diferent type?

should i pull bank 1 cam solenoid and check it?

any ideas
cheers

You should never clean the electrical connection plugs for the O2 sensors with contact cleaner, it can cause the sensors to stop reading.
