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
How long have you had the car? Fuel economy change could be anything, different fuel, tires pressure, weather, wind,traffic, how you drive, who drives etc. I'd try a better way of figuring fuel consumption. Going off the first bar isn't very accurate.
I assume you have a cvt. These cars shift much different than a conventional automatic and take some getting used to. I don't know about the 1.0l but the 1.2 can be a little weird as you come to a stop. It sometimes lurches forward once at a complete stop as it downshift. I'm not sure what you mean by the gear ratio increased? Is it reving higher than it used to at the same speed? Is your rad fan and/ac compressor kicking in when coming to a stop?
