Misfires
« 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.
Without traction power is nothing!
