Toyota Repair: problems after timing belt change, 1989 toyota camry, dual overhead cam

Question
My car is a 1989 Toyota Camry around 170,000 with a 4 cyl. 2.0 dual overhead cam engine. My timing belt broke the other day, and the mechanics tried to tell me it had bent the valves. As I cannot justify an $800 or so expense on a $500 car, I did some research and found out I have a non-interference motor, so this would not happen. I had them replace the timing belt, but my car is NOT the same. It now acts like it wants to stall out at stop signs or at slowing down, and the accelerater feels very stiff on take off. The car is now very slow to accelerate, and does not appear to be getting the same rpms as before needed to shift, whether in o/d or not. I do know that the alternator fuse was also bad, and we have not found a replacement yet, but is is wired past it for the moment and I do not think this could be causing the extreme change in the car. What did they do to my car?

Answer
If you had the same mechanic that told you that the engine had bent valves because the belt broke replace the timing belt then I'm not surprised you are having a problem.
My best guess is that the timing belt is not installed correctly, the timing is off, have them recheck the the belt timing to make sure the timing marks are aligned correctly. Let me know what happens and I can help more if necessary.
