High Engine Oil Pressure?

The problem started when I replaced my sparkplugs about two weeks ago. I replaced them with the E3 Diamond Fire Plugs I put them on and I had one bad one so I drove it in to replace the plug, it had high oil pressure which I figured was normal since one cylinder was not running. Replaced the plug and now every other start my oil pressure is through the roof and I have no idea what the problem could be I changed the oil two weeks before the sparkplugs and I had no problem. Any ideas or solutions?

Re: High Engine Oil Pressure?

Check the Oil Pressure Sensor. Those seem to go out sometimes. Also check you Oil and make sure your using the correct Oil which should be 10W30.

The E3 plugs are in my mind definetly not performance plugs and will never use them again. It mad no difference on performance or fuel economy. I will use either NGK or Bosch thin wire racing plugs because the E3 are not designed correctly to help ignition.

Thanks for the help on the oil pressure sensor guys, now I have something to do this weekend.
