How to clear coads P200C unknown DTC i unpluged a wire on exost and truck quit runing and wont start now
SOURCE: coad 1391
The code 1391 is : Intermittent loss of CMP or CKP
You are losing either the cam or crank sensor intermittently. Test and replace as needed. Check plug ends first.

These are misfire codes.This means that your vehicle is missing.The 300 is a random misfire and the 305 is for cylinder 5,and the 306 is for cylinder number 6.Check the plugs if they are good then you could have bad coils.They are top of the plugs.Hope this helps.Good luck.

You could have a faulty Fuel injector problem with your poppet valve. There common to go bad and start to leak causing misfires and ruff idle. There is an upgrade to the CSFI to covert to MFI system.
Here is a link that should help you with your P0304: http://members.shaw.ca/betterthanyoutoo/Sticking%20Poppet.htm

More than likely, you've got a leaking or deteriorated PCV tube connection (hole in a vacuum hose) which will cause the engine to run a little rought at idle. Look for a small hole in any rubber hoses between the PCV valve on the crankcase and the engine's intake near the firewall at the back of the motor. This should resolve the PO174 (fuel trims) code and PO300 (misfires). Also the PO1153 has to do with exhaust sensors and since you've changed the sensors you probably have an exhaust leak before the sensor, probably a bad exhaust header gasket.
