Hi

Jerk on gear shifting
The story behind this

1. three months ago my car had an issue with idle up speed. With AC or without AC the engine RPM was rising about
2000 and coming back to 800 within 2 seconds. Then it was repaired, the Idle up units was stuck. It was cleaned
and Petrol filter were replaced at the same time

2. Few weeks ago there was a misfire while driving. Changed the spark plugs, cleaned injectors and replace the air
filter as well.

Now i can see the petrol consumption somewhere 8Km/L . And the sparkplugs are bit a brownish and carbon to the body, please see the picture.
One guy said the distributor is faulty and to fix this you need to have new distributor.

When i shift gears form 2nd to 3rd ,there is jerk coming and when i accelerate on 3rd and 4th gears The engine gets shake, and then only raised the RPM ,in 1,2 seconds. But not instantly. This is new issue.
The spark plugs colour was pure white and it was like a ‘coconut’ previously (8 months ago). also i can remember the engine was shaking when i accelerate on the morning( cold) and if its warm it doesn’t shake.
Can you see any combination of all this issues? Or those are separate issue?
