This sounds like a timing issue. The timing could be off, or there may be a problem with the correlation between the camshaft sensor and the crank shaft sensor, or maybe the timing chain jumped time. If you know anyone with a scanner, it would help to retrieve the trouble codes. This would let you know what is going on.

I agree. It could be a whole bunch of things. Scan it for codes and then decide if its worth spending a bunch of money on. It's an old car and not worth much. Unless its low mileage and in minty mint condition it might be time to move on to something a bit newer.
