Your 94 grand Cherokee will not idle?

Answer 1

This is probably a vacumn line issue but it could be any number of other things such as fuel and electrical. I know this doesn't help you much but with what you've provided there isn't much more that can be said. I would recommend that you get a friend to keep the engine running while you listen under the hood for hissing sounds that might indicate a vacumn leak. You might also get a can of throttle body cleaner spray and spray it down the throttle body (this is on top of the engine where the air tube goes from the air cleaner). If those two things don't help at all then.....hmmmmmm.....take it to one of the big name parts store and ask for help. Usually there will be a smart guy there that wants to help and also wants to sell you the part that will fix the problem. I use those folk all the time and they oftentimes will come out in the parking lot and help you install what you bought. Last, but not least you can always fall on your sword and take it to the dealer. If you get it fixed yourself you'll learn something that you can share with the rest of us here and you'll feel righteously pleased to have done a manly kind of thing in a manly sort of way. Enjoy !!!
