My Toyota Altis 2007 nocks a lot even if gently accelarate in slow speed, One thing I noticed that when I push the accelarator from stand still it dose not nock a lot but in a slow speed in traffic as I try to accelerate moderately it starts nocking. It's over 250k on odo. any suggestions

Oil levels? Spark plug replacement history? Check engine light on?

No engine check light. Not sure about last tune-up as purchased this around 15 months ago. Oil changed two time, first at the time of purchase and second a month ago. Air filter replaced. Just drive 3500-4000 km in 15 months. Nothing else.

Probably your fuel pump is weak and the fuel filter needs replacement

you may test by changing the fuel station - adulterated petrol & diesel fuel is sold at many pumps.
2nd possibility is the fuel filter sack inside the fuel pump is clogged needs replacment.

I normally get filled from Total Parco and tried PSO also with no change in the issue. Used to fill my YBR from the same gas station and having no problems with a good milage in bike so I am sure that this is not the issue. As suggested will try to get the fuel pump and fuel filter checked soon.
