Only picked it up tonight was running fine at first, came in the house for a few hours, when i start it up the engine does not sound at its healtist or even how it did when i picked it up, i pull away its hesitant and feels down on power, then i notice a orange light on underneath the rev counter, checking my handbook out i see it is the exhaust fume warning light
car is definatly down on power, the light is staying on but sometimes flashes on and off fast but never stays off, also the ehaust is back firing and petrol consumption is 22 mpg on average by trip
any ideas ?
