The issue I have is when I start it up and set the idle it idles fine but as soon as I give it gas the idle stays high for about 5 6 seconds then it drops back down to a normal idle. It now will stay idleing but it's odd that when given gas it stays idleing hihg for 6 seconds. I alread checked and the slide is moving free and returns home so that's not the issue. Any ideas?
