high idling problems..

[240_all_day]

i got a 91 240sx well i just got it starting after being rebuilt , the idle is around 1500 ive dropped it too 1100. i dont know what it could be maybe a disconnected vacum line?

yea ive got same problem after mine sat for 1.5 years without moving.... my idle will usually stay around 1400-1500, sometimes will go as high as 2000rpms, and then sometimes goes to 1000, id say 90% of time its stay around 1400.... i have checked everything else it could be, soo im thinking vacuum leak too.... probably going to just remove my egr to help narrow down vac leak....
