Fresh Recruit
Hi. I am sick and tired of the jerks that i have to bear from time to time at slow speeds in the first and the second gear and it happens below 30km when im cruising and suddenly it feels as if the fuel was cutoff for 4 to 5 seconds, but if i pump the gas pedal it revives with a bad jerk, but if i keep the gas pedal where it was it will take 4 to 5 seconds to revive. Can any body tell me if its the fuel pump motor or some electrical issue or may be an injector. HELP its extremely irritating.

N.B: It never happens when i pickup the car during a friendly race or drive fast. Only happens when im slow below 40 with a gap of at times 10 seconds and sometimes 2 or three minutes while im cruising.
