i think if the clutch is dead.. like ecu-man says the engine would rev up high and the car will just move slowly..like its bogged. To test out your clutch, shift it in 1st gear and slowly take the clutch off, if the car jerks hard, then ya clutch is still good... if it just locks in. then ya clutch is a gonna. But i doubt its the clutch. prolly something to do with fuel. Thats my guess tho... GOOD LUCK DUDE.
