in the morning when starting the car at competely cold temp, the car sputters and rpm doesn't reach 1.5 . it'll sputter from 100rpm-200rpm and die if i don't hold the gas pedal down to give it some help. i would have to hold the gas down to 2k for 30sec-1min in order for it to somewhat stay idling. i've just removed the FITV and tighten what was necessary. i've replaced IACV, TB ( came with sensor / fitv ) , fuel filter, spark plugs 2-3months ago. TPS sensor reads .50v with ignition on. also, when the car is fully warmed up to operating temp and i'm at a complete stop the car will idle from 650-750. the needle will move in a very small moments, but within moments the car will drop to 100-200 and sputter. giving it some gas will bring it back to 650-750 and it'll just bounce frome 650-750rpm. there is no CEL. last code it threw was TPS sensor and i just replace the entire TB because it came with the sensor. car doe not have high idle issues.
the bottom hold inside the TB does not suck when it's fully warm so it can't be the FITV, i don't think? car smells like gas even after full warm up, possible exhaust leak?
answer will be VERY much appreciated. please help

 

IS YOUR O2 SENSOR HEATED O2? YOU MIGHT HAVE AN INTAKE LEAK. SPRAY LITTLE WATER ON THE INTAKE MANIFOLD AND SEE IF THE RPM CHANGES! GOODLUCK
