my car an 87se was idleling and i was messing with the idle screw .......it must have been like 5 whole turns down into the manifold and when i unscrewed it i heard my intake drawing in more air the more i unscrewed the more air i heard until i took it out and it stalled out......i figured why use it....i took it out and covered the piece where it sat with that black nipple so it didnt draw any air in......took her for a run and she pulled nicely.....just wanna know if this is safe running without or screw or not???thanks for your help buds
