Started with wrong oil filter causing low oil pressure. Then driving on highway the low oil light came on, Stopped and checked the oil, it was fine so I headed hoe. Then the car shut off. I was able to get it started after it sat for about 15 minutes. Sounds like it is missing or running on only 3 cylinders (v6). Now it will only run at high rpm (no idle possible)and the engine light is flashing. Shut shut it down. What's wrong?

Scan for codes and check fuel pressure with a gauge first

For the p0300 codes, check compression on your engine it should be within 20% of each other if not you have a n internal problem. Like abad valve, piston etc. The 300 ocdes shold be checked by a professional however as these codes can be amultitude of things wrong and are very hard to diagnose if not a simple thing. The p0018 code is a camshaft correlation with crank position sensor which you cannot fix. This has to be done by a professional with a pro scanner to see how far it is off which maybe chain failure due to oil leakage.
