MIL illuminated...checked oil level, its fine. Advance Auto plugged in their diagnostic reader...it says "low oil pressure", but car is actually running fine; engine temperature does not budge. probably the sensor, is the theory
Check engine light keeps coming on, says #5 changed coil pack two times still missing, oil getting to spark plugs..
