Got a B20B in my EG hatch. When I start the car, it sits at 2000 rpm for about 30 seconds, then starts surging (or reving up) from 1500 to 2000 rpms for about 30 seconds and then it keeps surging but drops from 1500 to 2000, 1300 to 1800, 1000 to 1500, then 900 to 1400. If I let the car sit and run for about five to ten minutes it idles fine after its done surging. I thought it might be a vaccum leak, but all my lines are connected nice and tight. It started doing this after I removed all of my heater components (lines, fan, etc.) Would that have anything to do with this? Any help would be awesome! Thanks! Honda luv!

 

Really? Nobody? C'Mon!
