Now I have comp cams 262, headers, cold air, sct tune and the rest is stock. The car idles around 800-850, and for the most part idles perfect. But sometimes it just drops and stalls. I checked it for vacuum leaks and have none. Besides 9 out of 10 times it idles perfect. I cleaned the iac and still no change. Just wondering if anyone has had this problem? Also one more question while I have your attention, after I drive it for 15 mins and shut it off it has a hard time starting. It has plenty of power but cranks over and over with what seems like no spark. After I try for a min or two it starts just fine, I think it might be a crank sensor. I think there are two and I don't know how to test them. Any help will be appreciated.</p></blockquote><p></p>
