I AM A CHRYSLER PARTS/SERVICE MANAGER AND HAVE SEEN THESE TURBOS BLOW INTAKE TO PLENUM GASKETS. WE ARE A SMALL DEALER AND HAVE SEEN 3 HAPPEN AND ALSO WAS VERY DIFFICULT TO DIAGNOSE. WE WERE ABOUT TO PULL THE HEAD ON ONE WHEN WE FOUND THE GASKET SUCKED IN. PART IS CHEAP AND REPAIR NOT TERRIBLE .HAVE YOUR TECH SPRAY CLEANER AROUND SEAM BETWEEN INTAKE AND PLENUM ENGINE SHOULD DIE DOWN WHEN YOU HIT THE LEAK

If the plugs get wet, then you have a spark problem somewhere in the ignition system. Pull a spark plug and hold it against a ground while you turn the engine over. You need to see a fat blue spark. If not, check the distributor, spark plug wires and coils. An easy way to test for spark is with an inexpensive spark tester. This is a device that is readily available at most auto supply stores. If the plugs do not fire properly, check the spark plug wires for fraying or cracking. Next, you need to check the coil(s). If firing voltage is low (weak spark), measure the coil primary and secondary resistance with an ohmmeter. If it is out of specifications, replace the coil. Also, make sure the coil is receiving normal voltage from the PCM or ignition module. If it is low, check the charging system for anything that may be reducing alternator output (battery and alternator cable connections, ground connections and voltage output).

Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
A code P0300 may mean that one or more of the following has happened:
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.
P0032 and P0038 are both of your Oxygen sensors that have gone bad and need replacing, make sure that you go OEM on these parts. Parts houses usually have something different and they sometimes work and sometimes dont.
