Hi guys,

just doing some checks so took apart the coilpacks and checked my spark plugs... and note my car only has done (54,000kms).






I was told that with if tip is gray and those burning marks means my car is running lean?? Car does feel laggy sometimes... could it be wrong air/fuel mixture? Does everyone else looks similar? Is this normal?



But today i have bought all of this and plan to do a full service myself... Might reset the ECU when i put new plugs in and see what happens...
