[JDM_RPS13.5_SR20DET]

hey so i havent heard anything about this and dont know whats the problem. basically my car was running about a week ago but the oil pan was leaking bad so i finally just got a new oil pan in today and put that on. but over the last week i have removed my ac and done a couple other things. anyways i go to start my car and it starts up fine then when it idles down it stalls. i checked the ground and everything to see if the injectors stopped. ground seems fine. when i rev the engine the engine runs fine, so the maf must be fine and so is the fuels system. as soo nas it goes to idle down it stalls. Any Help Anyone Thanks!
