Clio 172
Hi I just joined after after a long spell out and I just bought myself a clio 172, just got a few questions if anyone can help me? When the car in ticking over and running in low gears it's quite lumpy and you can smell fuel? It's says it's been remapped before and wondered if that could be the issue? Also I just had a scorpion exhaust taken off also wondered how much I could get for this is I sell it? Thanks in advance graham
