I have manual diesel sorento that for the last 6 years has performed flawlessly. However, last week the following happened 3 times in 1 trip.
I was towing my exhibition trailer (approx 2.3tonnes) and when I tried accelerate from a roundabout, junction or go up a steepish hill the engine would "feel" like it misfired, and would then die when I depressed the clutch. Turning off and restarting and all would be fine. After the second failure I noticed that the engine check light came on. After the third failure I completed the journey by ensuring that I did not put the engine under any undue strain (under 2000 rpm),
Once I reached the destination, I unhitched the trailer and use the car normally. I also noticed the following day that when I started the engine check light was out, and stayed out.
After completing the event, I towed back and deliberately avoided any strain, and had no failures and the engine check light did not illuminate.
