So I got my Lupo back in June. Its my first car and I loved it but ever since I have had it its been nothing but problems. About 4 weeks ago I ended up having lots of battery trouble which then lead to me breaking down. This problem turned out to be the alternator which cost me £300 to get it replaced at Halfords. Since then the car just hasnt been feeling right to me. To start with when at traffic lights it constantly feels like the engine is having power surges and it worried me that its going to stall all the time. It never has just feel like the engine is struggling to keep going. Today when I drove it....It hadnt been driven for a few days and the exhaust emisson light thing came back on (It had been on a month back but went off) Its usually stays on constantly but this time it decided to flash a few times. The engine whilst I drove it the short distance also didnt feel right at all...kept surging and then every so often the rest of the dashboard error lights would flash up for literally a second...and then all go back off again??? I actually cannot afford to have it looked at. People have told me it may be a filter that is blocked in exhaust system but woudl that cause the issues with the engine sounding funny??? Any advice would be greatly appreciated....as you can probably tell I am awful with cars!!
