2002 Mitsubishi eclipse won't idle

I have a 2002 mitsubishi eclipse gt that will sometimes start up and run decent but 10 minutes later will start up and the idle will be wild. pulsing from 800-1500 rpm and when ou give the car gas it dies. i have put new crank sensor, distributor, rotor, cap, wires, and plugs. any ideas would help out alot. also have checked compression. have 120 on 5 cylinders and 95 on one. book says 90 is required. only codes its throwing is P0335 & P0340 which are the cam and crank sensor. need to get my gas saver running Asap!
