Cultus efi jerks when release accelerater

[hassantahir2]

bhai muja efi cars zeyada easy lagti haien. carbs are much difficult to maintain. efi cars are straight forward.

Bss mujhay EFI car's ko sensors wagaira ki waja se hath laganay me darr lagta ha k aisay hi ECU fry naa krr du..
Carby me aisi koi tension nahi.. Aur ma Suzuki ki almost sari carby car's k sath thora bohat khel chuka hu FX, Mehran, Margalla, Khyber, Alto, Pothohar, Cultus(carby).
Carburetor ki setting karna to meri favorite hobby ha. Lekin first time karnay walay k liye bohat sir khapai wala kaam ha.
Agar aik dafa samajh aa jay to phir carby car ko kahi road k kinaray bhi easily wires direct krr k chalaya ja sakta ha agar koi problem ho EFI thora himmat wala kaam ha...
Though EFI car's are much better in efficency, performance and emissions.

Hahaha bhai apne suzuki pe kaam kiya hai try toyota A series carbs. They totally operate on vaccum. It's unable to work on them without diagram.
Nae bhai ecu nae jata itni jaldi. Ap ayo efi ki taraf it's alot easier. You know you can't set carb to ideal while living in pakistan. But efi's are build to work ideal. No doubt moding a carb is easier then efi. Because almost every mode in efi is useless without tuning the ecu and these ecu's are hard cored (non chippable). Apka pas ecu pinouts ho ap har gari ko wire up kr sakta. Like i did. Easy and alot of fun.

Hi dear can you find out solution?

[aazzy1122]

Hi same problem with my cultus, have you solution

Is the speedometer cable working properly? The speed sensor withing the gauge cluster malfunctions if the speedometer cable is loose or worn out.
I had similar jerking issue in my car also and the speedometer needle was also a bit jerky due to worn out cable. Didn't have this issue after replacing with new cable, however it is a very labour intensive task.

[aazzy1122]

Yes dear my speedometer cable is lose and make noise on high speed. Are you sure the jerking problem is solve with replacing of speedometer wire??

[aminjafer5441]

If there is no other issue or engine code given by the car then this could be the issue. The engine maintains appropriate rpm with the speed of the car via the speed sensor so that while gear change etc. the rpm doesn't drop below idle rpm and engine functions smoothly. My primary issue was with this cable as it came loose from the gearbox side.
Also you might be able to reuse the original cable cable as I have but it takes much skill and effort to regrease and reinstalled the cable as you literally have to open the whole Guage cluster, fittings and steering wheel assembly to get to the cable attachment.

I changed my gear box then the problem solves . The quality of cultus gear box is pathetic. My faulty gear box also make noise like " goonj"
