@saboor73 suggested O2 sensor issue due to engine light and speedometer behavior (it is while driving. This episode starts with the engine light, then the needle thing and goes away in minutes). I will visit 3S for this. Is there any other choice?
My 55KM car checkup is due. What other precautionary checks would you recommend at this stage before going for a 3000 KM trip up north next month. Inshaallah.
I'll post engine foundation snaps soon.
