My problem was the following
I am an owner of a mito 1.6 jdtm with 150.000 km
At last 1500 km i have a hesitation between 1800-2200 rmp on very light throttle.
Hesitation appears and dissapears i dont have it always.
Also at the same period i noticed one blowing noise ,when i am accelarating quickly, from the right side of the engine.Noise is like having the window of co passenger a little open.
Noise also doesnt appear continiously.Sometimes i have it and sometimes not.
I notice often smoke coming out of the exhaust while driving,and when i see smoke ,i drive to high rpms ,and the smoke doesnt appear again for some days
Also i have some smoke whe the car is cold at the morning.
Today i went to my service technician but he wasnt available so i arrange a check for this problem and also an oil change on monday.On my way home i put dna on d i accelarate third third up to 4000rpm and suddenly i had engine light yellow and the message that d and a of dna are not available.
I stopped the car and i will go for check on monday
The car is used i have it only for 15.000km
I have full service history and invoices for last 60.000 kms and i have noticed that diesel fuel filter has not been changed.
Also at the last car check technician told me that DPF cannot go under 45% filled after regenaration.
Car is acdcelerating very good and hesitation problem never apperas whine accelerating with heavy throttle.
Technician checked that lamda sensor was not responding,we have changed it car was working good for 3 days and today again i had black smoke at 3000rpm loss of power MCSF error and DNA not available.
Hesitations at light throttle after changiong lamda sensor never appeard again.
What do you thing is the proble?i suspect it was a double proble.lamda sensor and something else.
