frozenwaffles Posted May 13, 2007 Share Posted May 13, 2007 Hi everyone, i have the strange idle problem thats bothering me. i have now put my idle at 800rpm AC off and 900 rpm AC on. i have poer fc and have adjusted the aac/idle valve. i also have a gfb stealth fx bov. with the idle up where it is and nothe factory 650rpm reccomendation, she behaves quite nicely. i was having a problem where when you would take your foot off the accelerator when comming to a stop and the rpm falls from say 3-4000, it would drop below 500 rpm then climb back up to 650. this however would someties cause the car to almost stall. so with idle up higher and a check of the aac vavle (including a clean) it seems to behave. however today i had the same thying happen again... its annoying cause i am sure this should not be happening... changing from full atmos to PB on the bov does not seem to make a difference, plus i have tuned the bov as per the gfb intructions and it does not seen to cause any idle issues. so deos anyone have any ideas???
