Misfire! ,go for diagnosis to investigate the reason for this

No misfire code seen even the tachometer as I said is steady. The vibration is just when the car is engaged in drive but once it starts moving it's stops. The check engine starts blinking alternately with vsc once vehicle is started.

not all issue will always be reported as code ,if it is very fast and intermittent ,your fault management system will miss it and cannot code it .
there is something that is triggering the misfire which u need to find out why ?that is where the diagnosis come in and this is not a forum talk ,find a recommended technician to do this for your .

Will do that. Thanks

As long as it's already blinking, and not solidly lit on the dash yet, tells you there's a problem already with the car. Blinking lights, especially those, would begin by that blinking, warning you, before it develops into a hardcore(where the lights stays on)

Fixed

@ op Diehard 1, please how was it fixed, educate us for reference purposes.

Car was taken for around 10km drive at high speed, more codes came out. Running lean and multiple misfire plus C1202,. Plugs changed misfire disappeared but can was still not moving quick and still had C1202, then changed the fuel pump after that only check was blinking and VSC steady, code cleared and the car is now accelerating well. Almost drove me nuts. Thanks to all that gave me sugessions

I thought u said no misfire before .

I took for a 10km drive at top speed as I pasted above before it came up. I put all I did up there and thanked all of you that gave suggestion too.
