2006 Chrysler 300M 5.7 Hemi, all of a sudden the oil pressure has dropped to "0" when in idle or at a stop sign, and the light comes on, then when accelerated the light goes out and pressure resumes, and then now the check engine light is on any ideas? oil is changed every 3k miles and there is no engine knocking or tapping very good car until now. Thanks in advance

The check engine light means there is a trouble code stored in the car's computer. The first thing is to get this read out, to home in on the problem. Autozone will do this for free I believe.
It is not uncommon for the oil light to flicker at idle when hot, as long as the pressure rises OK at revs. Get an oil pressure reading done by temporarily replacing the pressure sender unit with a pressure gauge, and you can then tell if there is a problem in that area.
