AOA Adnan Brother,
Sorry for getting out of touch for long time, i was abroad for some time.
my racer missing / jerking (on petrol) after driving 3 to 4 km , do not pick acceleration and engine turns off. i start again, it starts in half self and drive 1 km and again same problem. if i switch to CNG on first jerk it continues to run smoothly ( i have little CNG filled from Haripur)
later on i realized that if I turn OFF/ON petrol switch (neutral position then again on petrol) on first jerk ( even do not shift to CNG) and turn on again jerks finish for about 1 km then on next jerk i turn off petrol/injector it solves problem for a while. I realized that it is fuel pump or inline fuel filter problem. i checked filter it was ok then i replaced the fuel pump.
by replacing fuel pump solve the problem but after driving almost 50 km little jerks whenever i switch the gear, pick has reduced as well.
i went to Khalid, scanned all the sensors , all sensors are working fine , everything was ok on idle (car standing position)
but again when i moved out of I-9 pick still reduced jerks during gear shift.
what may be the problem?
is it injector? or some other problem? i have not checked fuel pump pressure by proper gauge but visually it is very good pressure.
guide me in this regard.
khalid retarded timing a little bit now timing is around 15
