Hi,, the omega has 3.0 cats and down pipes but its a 3,2 . so i need to fit the extra lamba sensors to each bank of down pipes . looking at the position of the lambas i can see its the front sensors that need fitting . which means i will need to remove the down pipe first to fit . so my question is does it matter were the sensors go due to the fact that there is no front cat ... Thankyou
this particular 3.2 omega has got the earlier exhaust and cats fitted from a 3.0 so only uses 2 lambda sensors is there any reason somebody would do this Thankyou
HI,, ok passed the mot emissions . but its still misfiring at high rmp it then continues to misfire on what feels like 3-4 cylinders and then as you drive at lower speeds it gradualy comes back on 6 cylinders any ideas thankyou
ok thanks ,., just tried that and no difference. when you start from cold the engine revs are low. usually when you start from cold the engine revs are higher due to the cold start operating
