car started playing up again
wont rev above 5500, no performance and very poor acceleration
eventually eml light came on and went off again
only code stored is P1516
no other codes as eml aint on
any ideas
the lambda sensor readings are all over the place especially the post cat lambda which is sitting at .8 volts, the pre cat lambda is going over .8 and when accelerating the post cat lambda is hitting 1.3 volts
