Engine codes need some help

Hi All:

I got my codes read off an OBD II scanner and got these:

P0302--Cylinder 2 misfire
 
P1415--Manufacturer Control
 
P1319--Aux. Emission Controls
 
Any ideas on what to look at/replace?  Thanks in advance!

How many miles on your engine, has it ever been tuned, what octane gas are you using?

Hi Mike:

The car has a little over 86,000 miles on it.  I believe the last time the plugs were changed was at 60,000.
 
I always use 91 octane.  The car still idles and drives perfect.  I cleared the codes yesterday and they came back on today.  Any ideas?

Thanks again!

I believe that if you get rid of the old plug wires, going to the Magnacor 8mm wires, you will loose the misfire code and once it is gone the others will drop off.
