Hi guys,
I have just bought an 03' is200 just over a month ago. The car has ran flawlessly up until a few days ago when i noticed they car had become jerky when being driven, almost like it wasn't getting fuel.The car did however have around half a tank.
Over the next few days I have noticed the car revs funny on idle and splutters, almost like its missing a cylinder or again not getting enough fuel. When driven the car jerks at low rpm however this continues in all gears, not just the low ones.
I have read a few things on the forum threads here however im not entirely sure what is the main cause. I don't want to be wasting money on parts I don't need. Ive read this issue could be anything from plugs/coil packs to gearbox/clutch . I don't think it could be a problem with the clutch as I was told by the previous owner a new one had been fitted and the car serviced before sale.
The car also came from a family friend so although no paper work supports this I am in no doubt the work has taken place.
I did read that the IS should have been serviced with Iridium plugs and I am still waiting to hear back on whether this has been done.
The car has covered around 100643 miles if this helps ?
It annoys me as this car has ran silky smooth up to this point and I feel its getting worse, any help or input on this matter is greatly appreciated !
Thanks
Glen
