If your speedometer still functioning, the jerking you mentioned sounded more like below. Otherwise, the 1st thing you should fix is the speed sensor. Cap ayam RM70~80. Renault original RM250.
1) Clutch cover lose tension. Nobody is going to sell you the cover alone, so you'll have to change the whole set. Recommending Renault original clutch kit full set together with release bearing at less then RM400. However, workmanship is slightly expansive, should be RM250.
2) If the jerk happens everytime you put down your foot no matter on still/movement the car will jerk for awhile, it could be the throttlebody. Throttlebody clean RM20, ECU reset throttlebody position RM50(must do after clean throttlebody). Replacement of used/recon throttlebody RM250.
3) If you're also simultaneously having difficulty to start. Plot the key to START, and you hear the starter kicking extremely fast as if the engine is not there, until several attempt then only it back to normal? When you have this problem, and the jerk does not happen EVERYTIME and only once in a blue moon, then it could be the TDC magnet is weak. RM80 for the part, replacement labor should be RM10~RM20/
Hope this help
