Everything I can find on this car states that it has an "interference engine". This means that, given your description of the problem, there is likely to be catastrophic internal engine damage - bent or broken valve(s), possibly damaged piston(s). I hope you didn't already pay 'this man' for the "repair" (engine modification). - Good luck. p.s. Just for my own information, I tried to look up the current value of this car on a very popular web site (rhymes with "belly poo look"), and it wasn't even listed for this year.

If it ran before he replaced the belt, and not after wards, He miss- aligned something. If the belt broke, and was then replaced. The engine may have suffered some internal damage.

He may have put it on wrong, or left something disconnected. I would find another man to fix your car.
