Got the d15z1 fully swapped into my crx. Engine started up no problem, no cels. Engine idles great, revs fine, but has a hesitation/surging problem around ~1500rpm at part throttle (think trying to take off in first gear). Have gone through all the vacuum diagrams and everything is hooked up right. Any ideas? Oh yeah, idles at ~600rpm, timing is set, and vacuum is 15psi at idle.
