Aslam-o-Alaikum,
I have Suzuki Wagon R Wide 1997 K10A Turbo, I recently had gear issue so i have changed the automatic gear "got use one from reliable source" . Now the problem was there before but it didn't happen all the time, the car jerk like its applying a hard break it self in cold start or low gear, then when it warms up or in high gear it run smoothly, but it use to happen some times, now since yesterday i have changed the gear the problem happen every time when I start it, it jerk like applying very hard break all of sudden in low speed or at least driving it for about 3km then problem goes away or remain but very mild jerk in low speed.
The mechanic who have done the job have checked following so far but couldn't find the cause
1: Fuel tank, thinking it might be dirty, but surprisingly even its 1997 model the tank was like new and same goes for the pump and fuel filter
Breaks and complete system related to break checked, No issue found, As first the mechanic taught it can be break related due to some engine exhaust or something
Sensor and other test using diagnose tools, all cleared
Plugs, all checked it have its original plug and nothing seem to be wrong
Throttle body is clean, he tried it to tune it too today but it doesn't help, i might get it changed it and ignition coil as well tomorrow.
Having said it all, i don't think even changing throttle body can help it, i Googled alot about it, some are even saying it can be battery issue, or not earthing (ground) wires properly, can any one having or faced the same issue, or give any hint or let me know any experienced person who can solve it in Rawalpindi or Islamabad
