My Roadsport with the Sigma 150 runs well 99.5% of the time, but recently I've noticed that if you stop for 5 minutes (to buy a paper or some mik) the engine runs lumpily on the restart (to the extent it will stall if allowed)
Its almost as if a couple of cylinders aren't firing. After 20 seconds or so of increased (lumpy) revs, it sorts itself out,, the cylinders kick in, and runs as sweetly as ever.
So not a major problem, just a niggle.
Any ideas ?? I did think that it may be fuel evaporation due to heat, but when it is running lumpily there is a smell of petrol from the exhaust so perhaps fuel is getting though ??
Over to the power of Blatchat................ Thanks
Final Update 23.06.09
Please see post on 23rd June, after the latest map, Rev H, car is now fine and was had a dyno run at Northampton Motorsport. Figures are more than acceptable, so I'm happy again 😬
