u can DIY wash the seats yourself... if it is fabric type... just buy the dry foam fabric cleaner. I got mine for RM16.90 and it works on my carpet tho... the stains are out...
I Have a 4G93T 1.8 GDI in Lancer and the engine is pinking some times, I can only get 96 octane fuel, can I retard the timing by moving the crank angle sensor on the exhaust cam, or is there some other way.
