Hello.

I got Mirage 2014 - 1000cc imported from Thailand. It has done 16,000km to date.

For the past 3 weeks, i have strange problem.

The fuel economy has dropped dramatically. Before the first dot of fuel indicator use to go off over 90km driven, now it is at 60km.

Things i have noticed while driving.

Acceleration is still good. But when i ease my foot from the accelerator to slow down, RPM drops with a light jerk. Even at slow speed of 20 - 40km/h, there is some sort of hesitation in slowing down.

Also, the gear ratio has increased a little bit.

Also, it happen after few kilometers when the car gets hot. In the rainy weather is it all good.

What could be the reason. I have cleaned the throttle body as well.

Also, what i have tried is that i stick tape to narrow down the air intake just after the MAP sensor, and car seem to run better and fuel economy also improved.

MAP sensor is all cleared. Air filter is brand new, oil change and oil filter is always on time. Transmission oil is all good, checked at cold and hot temperature.

Any help would be appreciated.

Regards
