<U>93lude vtec</U>; idle problem after i warm up the car. Idle sits at 500 rpm, when i tap on the gas pedal softly to rev a little then rpm meter falls down below 500 rpm and it seems to stall but stays back @ 500 rpm. Sometimes it would stall. I checked the idle screw and it seems to have enough air goin in by hearin the filter hissing. Checked all the vaccum line and it's fine. What could it possibly be?

On the <U>Vtec</U> situation, I test drive down the block, the vtec seems to engage @ 5,500rpm but i remember before it was @ 5,200. And theres one more problem to that, when the vtec kicks after 5,500rpm then @ 6,000 it choke for a sec then kicks again. What can that be, is the vtec mess up or what? Help this damn lude cuz i'm gon' sell it, drives me nuts.
