2005 s60 2.5t multiple cyliner misfires. changed plugs, cylinder 2 still misfiring and running rich. codes are not accessible by mechanic so its off to the dealer I go unless you have an idea. Thanks
plugs were all changed but ECU codes are not accessible by my mechanic. 3 cylinders were misfiring and it happened real quickly. Standing at a red light went to accelerate and engine started shaking and running real rough. o2 readings ok so cat convert seems ok. after plugs changed cylinder 2 still misfiring and engine running rich. Mechanic said need to take to dealer to read deep ECU codes rather than throw $ in parts at it. Any Help here
