    Welcome to Jeeps.net! Have you read the code yet? The code and any code history will help us help you. Some auto parts store may offer code readers for rent, purchase or perform the service.

    Welcome aboard! I agree with aggrex. Get the code read and let us know what it is.

    @aggrex The 95 is pre-OBDII code software. Is there a code reader for it?

    From what I have found, OBD 1 is for years 1991 thru 1996....?

    Because I like to play with YJs I have purchased service manuals for them. Couldn't play without them. Some of the more modern 80s cars and trucks had OBD1 as well I believe. From what i have read, the problem with OBD1 is that each manufacturer had its own coding so you had to have a code reader for each. OBD2 was mandated by the feds to make a universal code that was accessible by all more easily. For OBD1 you are supposed to be able to count flashes for code numbers, but I don't know the essentials of the trick. I will research this some more, but as of yet I really have not needed it.

    Welcome to the forum hoops8865.

    Well, your off to a flying start dude. You presented an issue we have not seen. And since I am in no way as knowledgeable when it comes to code reading and issues with older Jeeps as other members do. So Im gonna sit back and read this one and try to pick up tips that other members post. Can never be over educated. Is that such a thing. Lolll.

    Welcome to the forum Nick.

    Here is a perfect video on reading OBD1 codes.

    I read somewhere else that to get to the code reading mode in pre-96 Cherokees you have to turn the key 5 times.
