Tricky Check Engine Light

[RANDO CAMMANDO]

When i got my car it had started changing the obvious plugs, coils, gaskets stuff it need went to fail safe everyone knows that story. Then we went to new computer (covered warrenty) throttle body well everything got done said it was relearning check engine light on said after it cycles it will go off. Two weeks went by still on took it back couldnt find any codes said go drive the hell out of it real fast and come back and see if it gives us one said ok have some fun went played around still no code

Now the question Its been a couple months now ive disconnected the battery reset it stayed off for like 2 days still comes on no codes but the car drives great any one every had this happen? And what you do to fix it

any feed back greatly appreciated
