hi guys,
i bought a Vitz 2006 1.0 few months back. as per the mechanics its engine was weak. therefore i decided to swap it with 1.3 (2SZ). The mechanic told me that the 1.3 would be more economical and smooth etc. but now once i have swapped the engine its a different story :worried, the engine is really noisy, though the pick is awesome, but as you push the pedal it gets more noisy and the fuel average is never over 12 not even on motorways.
an expert opinion would be highly regarded.
stay blessed
