the car used to idle at 2.5. i cleaned the IACV but the problem wasn't fixed. the CEL was code 7. so i replaced the entire TB. right after i installed the TB and started my car it was shaky but at 750pm. No more CEL


Next day

when i first start my car after overnight, it'll rev from 2.5-3.5 but will slowly reduces it's rpm after it gets warmer and stay at 750rpm. at 750rpm, it feels like it's not stable. engine is quite shaky and sometimes it'll drop down to 200 but it'll catch it's way up. if i don't drive my car after 3 hours. it'll repeat the same step, reving from 2.5-3.5 but without the rpm dropping from 200. it'll stay stable when it's completely warm. even when it's fully warmed up, the engine is still very shaky and the sound of it makes the car sound like it's in it's 70-80's. Car blows out black smoke and some sort of liquid, but the black smoke isn't thick. It isn't throwing a code. Any Ideas?

I've Clean/Changed IACV , TB, Spark plugs, and Fuel Filter.
