The car wont go, the engine runs so roughly, I replaced the coil pack because of several misfire codes, it did not help but the misfire codes went away, I recently replaced the water pump which is timing belt driven three weeks later the car stopped running properly, could the timing belt slip cause these codes P0135 and P0341?
Code p0135 refers to a HO2S sensor 1 bank 1 heater control ---circuit malfunction- ===causes ---fuse --wiring and sensor
the other code p0341 would point to your problem It refers to camshaft position sensor(CMP) sensor A bank 1 --range / performance problem===causes --insecure sensor /rotor---air gap---wiring - CMP sensor
check that the rotor is fixed properly , that there is no dirt in the air gap and adjust the air gap. If it still plays up replace the sensor.

Not saying this for sure, but I had the same problem, and i have a 1994 xr7 V6 3.8 L , and all u need to do is set the idle down manually because your computer could have seen that the injector was stuck open, and tried to turn up idle to keep up with the amount of fuel being pumped, worth a shot :P

Disconnect the battery completely, try turning the key with the battery disconnected. Put the battery back together. The check engine light should be off now..
