[quote="Yowie"]Quality write-up!

Thank you Yowie.
I think my car's throttle body was never touched before. Only the intake side was cleaned. If routine maintenance would have been done before, it would have been in a better condition. I'm using 98octane fuel since I bought the car and Iv'e decided that I'll clean the throttle body every 10,000kms depending on the driving conditions.
