i just completed my d16z6 swap. to keep things simple i kept it obd0. vtec is not hooked up yet. during intial fire up it soared to 4500 rpm. i had to retard the timing so much to get it down to 1000 rpm. there is zero throttle response. i have to hold the throttle down for about 5-10 sec before the rpm starts to rise. any rpm below 900 rpm the engine starts shake like its bout to die. any time i align the timing marks the engine revs to 4000-4500 rpm and idles there!
