Once the car is warmed up it starts to missfire and a grinding noise starts, have just had the water pump exchanged, changed an o ring in the distributar and had a new power steering pump installed. It is worse going up hills. I am a single parent and dont have the money for a mechanic so any help would be gratefull.

If the noise is only while moving, then it could be suspension or drive train related. Check the wheel bearings, transmission fluids etc.
