Hello Carl, I have a Cherokee Laredo 4.0 1991 High output,AT, it needs the computer becase the last one is broken but I don't know what the number is and it doesn't have number, I bought one but didn't work, my question is, Can you tell me where I can get the computer number?

Thank you.

Answer
Roberto,

Your local Jeep dealer should be able to supply you with the appropriate part number.  Most wrecking yards, also have these in their manuals.  I have some questions.  Are you sure that it is the computer that is bad, or could it be some bad sensors causing your problems, such as a map sensor, or a throttle position sensor to name a couple.  I would take the Jeep to a reputable shop, and have them run a diagnostic on your system before you spend a bunch of money on a part that may not be bad.
