Finally good news for all you guys! during my last thread http://www.automotiveforums.com/vbulletin/showthread.php?t=887003 (check for more information).

How do I fixed it?..thanks to God + the help of nismo_pilot and slideways. I did the idle air re-learn (very easy procedure) I did it twice just in case...at the moment it kepts doing the same thing, next morning I went on the highway late to a meeting and I put the car at 120mph for like 40 secs...I guess he learned the lesson lol....

Thanks guys! have a nice week.
