my bad man it is 0351 i was just going from memory, on the tuner i used to read the code it actually had the code and the description. i just drained the oil. It was very light brown but i didnt see any milky watery seperation. I did notice very very tiny specs of metal though

You need to do a compression test.

^+1, yup...

The most likely cause for P0351, if the COP checks out, is a wiring problem in the red wire from the CCRM to the COP (KOEO there should be +12V between the red wire and ground), or the light green/white wire from the COP to the PCM; or a blown driver in the PCM.

Thirty seconds with a diagnostic scope will tell you which...

Before u have a catasrophic failure do yourself a favor and get the car tuned, a mail order tune for a power adder is a terrible idea, unless its already to late.
