Car very sluggish especially when engine hot or in jam.

ironheart:
I do frequent Kelvin pretty often. Like I have said, so far in one year I have already at least changed or done the following, all parts are new.

1. CVT Fluid
2. Original Spark Plugs
3. 4 x Ignition Cable
4. All engine mountings
5. Aircon compressor
6. Rear brake pads and drums
7. Air Filter
8. Amaron 45A battery
9. Throttle body cleaning
10. Engine and radiator flushing

The problem still exist every now and then especially in heavy jam or when restart after short interval after a long drive say 25 to 30 mins.

Seriously dunno what is the problem, the car will not stall, idling rpm also perfecting normal, it is only when step on accelerator, the car like constipated, move off damn slowly with rpm staying at around 1000rpm, refusing to climb despite foot already floored the pedal. After a few seconds then engine speed willing to build up..........slowly

It is very dangerous with such condition as you don't know when it will relapse, imagine it happens when one is turning and in the middle of a busy cross junction.

Sigh...

Jazz:
CVT gearbox going up the lorry I guess.


If changed CVT oil, remember to bleed fully else air trapped may also affect performance.

ironheart:
I dun think it is the CVT problem as yet as when the sluggishness happens, it feels like not enough petrol going into the engine and takes quite a a few seconds to slowly revs up. Once it manages to sluggishly rev past 1800 rpm, the engine comes alive and back to normal again.

pizzaboy:
Replace ur fuel pump & fuel filter see hw it goes aft dat

Jazz:
Not enough of fuel to the engine will cause jerking, same like out of petrol situation.

Anyway, you can take note of pizzaboy suggestions.
