I am a proud owner of a 2007 Hilux 2.5 Auto. For the last 6 years, it has served me faithfully and it has never given me problems.
However... recently (in the last 2 weeks), occasionally when I am stuck in traffic on a slope (uphill or downhill), the engine
I noticed that it happens when I apply the break, especially when the traffic is slow because of a jam on a slope, the engine sometimes shudders and convulses and then it stalls. It feels alot like if when you are driving a manual car, and the gear is set to the wrong one and without revving enough to cover the loss of power, the engine shudders and dies
But the thing is I am driving an auto truck. I have sent my truck to the toyota service centre 3 times already, but they are unable to replicate the problem in the workshop and they say that the vehicle is absolutely fine
Does anyone have any idea what could be wrong?
I would appreciate any theories
