Title: 89 YJ Rough Idle Issue
Post by: TheBrain on January 19, 2007, 06:59:31 PM
Bought an 89 YJ today that has a rough idle.  I pulled the fuel injector out and cleaned it up a bit and it ran good for about 5 minutes or so and went right back to the rough idle.  I have been told it could be the MAP sensor as well that causes this.  I have checked the vaccuum hoses for leaks and haven't found any yet.  Also, the TBI unit seems to make a fluttering sound when its running.  Could it be that I need to replace the fuel injector???

Thanks,
