Cleaned throttle body, n noticed a vortexed hole at INLET of intake manifold, clogged w/dried oil( coming from pcv valve my best assumption) has anyone ever cleaned this out, and if so, what did you use? I dug out the stuff best as i could, but of course do not wanna damage it, especially if there is a fine mesh screen at bottom! :) ( a thorough tune-up and it still has a slit miss ( i know millions of options lol......... i Thank you, FWIW My BII was HIGH idling would NOT come down ( had changed the IAC) Pulled solenoid OFF and the O ring was a JOKE, replaced w/fattest O ring i had, n problem SOLVED YMMV..
