hi,ive got a 2002 l322 v8 petrol model, problem I'm getting a misfire type problem only when the car is warmed up?and a sound like grrrrrrrrrrring if i stop the car and start in up no problem till it warms up again!!,noticeable mainly around 20=30 mph,got no reading of a problem on the dash,any help with this would be great,

You might need a diagnostic tool to determine which cylinder is misfiring - it's likely the systems have logged a fault. I had that problem recently on No.1 cylinder. I swapped the coil to No. 2 cylinder (very easy to do - see YouTube) to see if the fault went with the coil but it hasn't resurfaced. Ron B. VK2OTC

hi,thxs for the reply, just put in new plugs and coil packs all 8,

! At least you know how to do it - again!

Are they genuine coils or Chinese?

I don't suppose you have a GAP IID diagnostic tool to read any fault codes. A generic code reader may also work. Ron B. VK2OTC
