Dear all i have serious problem with my JDM wagon r mh44s. 2014 FZ model.
Car jerks during acceleration at low speeds like 20 to 60. Its more prominent upon increasing the load in car like 3, 4 people sitting or turning on the AC. Also upon load it some times its take time to shift the gears.
Below remedies are done to solve the issue but still in vain.
- Changed plugs
- Changed bonnet battery
- Borrowed coils form friend having same car.
- Cleaned catalytic converter
- Replace throttle body
- Used high octane for two three tanks
- Poured injector cleaner in tank
- Borrowed throttle body with friend having no issue in his car.
- Checked fuel pressure at injectors fuel rail.
- Reset ECU.
- Replaced air filter.
- Drove with out oxygen sensor.
But till now all of them are in vain.
Total Odo is 55k. Replaced cvt oil at 40k. Used aisin cvtf.
Engine oil using 0w20 of caltax. Previouly using 0w20 kixx.
One mechanic told me the your cvt has a slip. While other told me your throttle have issue. Another told me for catalytic converter have issue.
