Trouble shooting codes
P0302-cylinder #2 misfire detected
P0420- catalyst efficiency below threshold bank 1
P0340-No cam signal at PCM.
The Cam sensor most likely needs to be replaced first. Clear the codes after that and drive and see what comes back on.

I RECOMMEND REPLACING THE OUTPUT SPEED SENSOR..ABOUT 40 BUCKS..WILL CAUSE THESE OTHER FAULT CODES AS WELL

there are no reset codes, did you bleed the air out of the cooling system? if not do this procedure, if that doeasn't fix it u have a failed air temperasture control blend door motor actuator.
The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml ,

If the injectors are OEM for that motor then it sounds like your idle got knocked off or was adjusted to compensate for the old injectors getting worn and clogged. Look for you throttle cable at the intake manifold. Where the swivle is for the cable there is an adjustment for the cable. It should be a little round nut or screw.
