I would like to know if anybody would be able to help me with these four problems with my check engine light on my 1998 Dodge Dakota. The codes are:

1) P0141-Oxygen Sensor Heating Element Circuit Malfunction
2) P0301-Misfire Detected At Cylinder #1
3) P0441-Insufficient Or Excessive Vapor Flow Detected During Evaporative Emission System Operation
4) P0138-Oxygen Sensor Input Voltage Maintained Above The Normal Operating Range

The oxygen sensor codes have come up before and I am on my second set of oxygen sensors in three months. The misfire code has been coming up and I have put new spark plugs and wires in about four months ago. They were the Autolite Platinum plugs and Auto Zone wires. The vapor flow code, I'm not really sure what this is, but does any one have any idea of how I can fix ANY of these problems?
 
if you keep getting misfire cylinder #1 then it may not be a plug and could possibly an injector or intake leak at that cylinder.. see what you can switch from that cylinder to another to see if you can move the problem then you know what to replace. the misfire can also kill the oxygen sensor prematurely .. the po441 sounds like a bad purge valve or hose that connects to the purge valve. the po138 is caused by the misfire as well.. fix the misfire first then oxygen sensor because of heater circuit.. i would recommend a plain champion plug since its a dodge though they seems to work very good sometimes an ngk is good as well for dodge.
