Yeah, it did some "horsing" around like u described but only when im in idle or at slow speeds (<10 kph with feet of the gas pedal). Stops immediately as i apply some throttle...
I did came across that info abt the ECU's ... so far i haven't experience starting problems but a while back it tend to do this thing (though not often), where after filling up petrol, i start the car n the engine immediately rev up to 3k+ rpm on it's own... i had to turn off n re-start it to drive away normally. Lucky i haven't changed my muffler yet
For me it happens but after servicing at PSC it is ok n will come back again when near the service date. According to PSC, it is common for Saga FLX CVT.
Right now I am waiting for my ECU upgrade as claimed by the PSC, they said the root cause of why sometimes my car cannot start is bcoz of the ECU.
