I have a friend with a '89 Cherokee with a high idle issue. When he starts the Jeep cold it idles fine until it warms up. As it gets warmer the idle jumps to about 1700 rpm in park and 1,000 rpm in gear. We can find no vacuum leaks and when he unplugs the MAP sensor the idle goes down to where it should be. Any ideas?
Thanks in advance.
