1993 Plymouth Grand Voyager L.E. running rough after changing timing chain and sprock

[proscribe1993]

On a 1993 Plymouth Grand Voyager L.E. after discovering a coolant leak originally thought to be a bottom water hose, then a water pump problem, I discovered when changing the water pump, that there was a hole in the timing chain cover which the pump was attached to. I replaced the timing cover and discovered the chain loose so changed the timing change and the sprockets. Reassembled everything and when I turned the car on it ran rough and made noise that I had not heard before similar to an exhaust leak. Cant figure out why its running so rough and no check engine or service soon lights come on. Anybody got any ideas?

Hopefully it's nothing you did. To confirm, check compression, at least on the "easy" cylinders. If they're low across the board, cam timing is off.
