My car at cold idle is perfect. At hot idle it's perfect. My problem is when cruising and I put the clutch in to shift the rpms stick for a couple of seconds then go down. If I take my foot of the gas in any gear it's sticks at that rpm for a couple of seconds then goes to normal. I know about the idle checklist but the car idles great. Could this still be a vacum leak, IAC. EGR or throttle cable ? I'm going out today to start checking it out and thought I might as well ask to see if anyone else ever heard of this happening.
