Driving home about 30 minutes ago I pulled out from the New Forest on to the A35. It has traffic coming up fast at times so a decisive get away to join the road is always best. As I did so the engine warning light came on. I had started the car a few minutes previously and at that time the low fuel warning came on. The car is feeling slightly sluggish and reluctant to kick down and when I got home the idle was a little rough and it is reluctant to pick up cleanly from low rpm. Would low fuel upset it this much? The range to empty at the time it happened said approximately 32 miles.
