Title: Misfires
Post by: DomBacon on June 06, 2015, 06:57:50 pm

Car started to misfire last night, changed spark plugs and coil packs today and it's still the same!
Done a compression test and all seems fine there!
What else can I check?

Logging with vcds it will see if there's a miss fire on a cylinder or not

If it's misfiring on two cylinders after changing plugs and coil packs then it's usually down to faulty injectors or your inlet valves are badly coked.
