hi i have a 94z m6 and 50kmiles . she has being missing at around 5-5.4k pretty bad i dont know what it is and i changed the intake elbow cuz it was torn and i hope its not the opti.
the wires and plugs are stock (u think is time to change them?) could it be the plugs?
thanks

First think I would do is change your wires and plugs, high rpm miss tho sounds like you need a new coil, that alone might be your problem. You can pick up an off brand stock one at most auto parts stores for less than $20. Obviously could be opti tho to.
