2000 Acura Integra STILL NOT RUNNING 100%. ROUGH IDLE

A couple of yrs ago igot in an accident the front of my car was hit, it appeared to have only damaged my bumper, that got fixed and about a week after I got my car back I noticed the temp was high above norm only when I would come to a stop, I had to put in neutral or park so I can give it gas and only then would the temp gauge go back to norm. Checked the coolant level it was empty, I thought problem was solved, a couple days after that while driving down the freeway check engine lights up along with the temp was all the way 'h' I got off the freeway right away & then my car was covered in smoke from under the hood, car was towed and found out the radiator was cracked, got it replaced and back to normal for about a week, then my car starts to be rough when idle and taking off which led to having a clicking noise under my car. My symptoms at this point are rough idle, constant low oil (with no oil leak !) And no power, I had to basically help my automatic shift gears and my car top speed was pushing 60 if that 50-60 mph max. Ran diagnostics and came back with low threshold and 3 of my spark plugs were burnt. I was told I needed a catal. Converter, so I did as well as changed the air filter, new spark plugs, oil filter/change, new ignition coil, new wires, basically a tune up.I thought the nightmare was over, my car was running better than ever until a couple days later when I started my car my maint req light lit up and I noticed my car was rough at idle again, and my car has a rumble as if my muffler is loose or chugging. I ran diagnostics again and came back with no trouble codes, when we try to clear everything and reset the maint light it will light up within five minutes into driving can someone please help my ongoing nightmare oh and to add a little more to my disaster my car is late on registration(paid for) but the smog test is not done, because the technician said that regardless with the maint reqd light on its an automatic fail. And now my car feels like its lacking power again and the oil is constantly running low ( with no leaks) anyone please
