had an emissions light on or a couple of months now and not had time to sort it, but noticed today that im not gettin any over boost. when driven its just boosting to 8 psi and staying bang on ! had suspected the afm for the emissions but could it cause a lack of over boost ? are these two problems likely to be linked to one fault ? had the codes read when the eml first came on and it was fuel trim ( bank 1 ) any ideas welcome, i dont want to be replaceing loads of parts to sort it out ( the missus already moans about the amount of money spent on the car ) !
