I have the car about 3 months and the engine light has been on but the car is running perfecly and then 2 days ago the engine light turned off which I was relieved with but now getting upto 2000 rpm in first - third gear there are rubbing and squeeking noises coming from the car and when in 4th and 5th gear I can't put my foot fully on the accelerator as the engine just revs like in nuetral and nothing happens ( only sounds like my engine is going to blow up ) and now I cannot go faster than 40 mph could anyone tell me what is wrong and a possible soloution I would be very grateful.. Neil
