Hi, a few month ago, i have purchase Vitz 2008/2012 model, 1000cc, which have already driven someone 56000/Km. After that i change the engine oil, filter, nd also gear oil and used toyota oil. but now a days i am facing, some time one car is going to 20 or 30 km/h than going to slow down or much pressure on engine like going to stop the engine, if i push hard than no problem. Plz give me some suggestion, what will i do? thank,
Safdar
