Well I went against ur advice zef and changed the plugs out again with ngk tr55s.....the platinum tips if the 606s where completely gone after only about 150mls.....needless to say after replacing with the tr55s and driving for about 150 mls, the car is running better than ever......i guess the type type of plug has alot to do with it

How many times must it be said.... PLATINUM does NOT last in these engines. Iridiums is recommended by factory specs, or regular copper core autolights... NO PLATS!!!

But didn't you read. It runs better with platinum. Had to be the choice of plugs. 606s apparently don't work in our engines.
