i'd think it's more likely your coils are weak so not burning the mixture completely.

you reckon coz when i changed plugs today on two of them it had white colouring which i thought was due to lean mixture how would i be able to tell if its mix or coils n also in morning it was down on power n toxic gas light came on but went when i slowed down n been running ok since
