My car runs bad on normal fuel!!! - Any ideas
Recently I have noticed that my car has been running really sluggish. In the cold it smokes alot and it has very little power to go at. It's a 1.6 156 twinspark 2004 new shape. Anyway when I put in high octane fuel it is like a different vehicle, it runs smoothly, doesnt almost stall around corners and I can actually feel some sort of power delivery. The fuel consumption is not great and the oil consumption is quite high. Does anyone have any ideas on what this could be??
Your thoughts would be appreciated :-)
