Dampness in the plug wells potentially.

mine does pretty much the same thing , except does it all the time

i put mine down to the idle air control valve , i bought a replacement 2 months ago , but have yet to fit it so can't be sure

where abouts is that mounted

it is underneath the throttlr body , getthe car hunting , then unplkug the grey plug going to it , the revs should rise to about 1000rpm and stay constant , if they do then 95% sure its the idle valve

if not maybe you have an air leak . didn't you go back to stock bov , if not maybe the dumpvalve is leaking/requires adjustment

could be a vacuum leak.... I had a similar problem with a leaky hose on a crx
