Here's what happened and what I have done so far...
I changed Breather Cover out cause the sensor cover was broken on it (wasn't really having issues at that time) a few weeks later Alternator got fried cause the negative terminal was loose and I didn't know it (no idea how long I been driving it like that), changed the alternator to find out the battery was also fried as well... battery that was in it was Autocraft 65-2 850 CCA... didn't have time to get back to Auto Parts for new one at the time so I put my Autocraft Marine Battery in it, which is a 650 CCA, all run fine except the light, after the car sat for the night the light would come on, once I drove it about a mile or two down the road it would go off... Drove it like this for about a week and fuel pump went out so I changed that and got the right battery same as Original, changed the cables, terminals and all fuses and relays... Still have the Indicator Light Issue... It comes on if the car sits for a while and goes out once I drive it... Had Charging system checked twice by two different auto parts and both machines showed my system is charging normal...

Test Show:

EXP Decision Results: Voltage 12.00V, Measured 819 CCA, Rated 850 CCA, Temperature 117deg F "Battery Meets or Exceeds Industry Specs."

Starter Test:
Cranking Normal, Voltage 11.20V, Amps 335.4A, Time 546mS

Charging System Test:
NO PROBLEMS
NO LOAD 13.90V, 79.4A
LOADED 13.48V, 44.6A
0.24V RIPPLE 122mV -0.24V
Charging System Output Test Normal

Everything seems to be running fine but that light drives me crazy... Any Suggestion as to where to look?

it sounds like you have a short. it can be a real bear racking it down. i would utilize the fusebox to eliminate individual circuits, track down that voltage leak. it could be a component or inside one of the computer controls. but you should be able to trace it. may take awhile.
i had a vehicle doing same and i finally tracked it to the overhead coucil, a circuit board had become delaminated and broke a cicuit, shorting out the next one to it.
