Dodge Repair: oil light flickers,engine light comes on, engine oil pressure, oil pressure switch

Question
QUESTION: well it goes like this. i rcently bought a 99 intrepid with the 2.7l. i had basically the whole engine rebuilt, i bought timing chain. crankshaft, rod, rings, lifters, oil and water pump and more stuff that i cant remeber. anyways,i took it for a spin and about 20 minutes of running it started making a knocking noise(fixed, changed to thicker oil, lifters emptied out)ok, all good. so my engine light comes on and the oil light starts flickering. oil light goes on and off at idle at times, and same when running. i know, or at least have a feeling that is low oil pressure, but why if had new oil pump and new pressure switch? now the engine light still comes on but dont know exactly why. well a/c went out too before a radiator cooling fan went out, do they relate to each other? any suggestions would help for all of the above

ANSWER: find out what the code is for the engine light and we can gp further.I live in ATlanta
