1998 Jeep Grand Cherokee Stalling Problems
I too own a 98 GC and have had this problem every winter since purchase. I have had the computer diagnosed and replaced several components according to the code hoping to find a "cure", only to have the same prob and new code pop up weeks later until the weather is finally warm enough to not have an issue. I did find there is a recall for this situation you can find it @ http://www.consumeraffairs.com/news04/2008/03/nhtsa_jeep.html
I am calling Chrysler to see if the recall is still open and valid. However i do have to say a friend of mine who happens to be a machanic told me '98 was a bad year for jeep, there are several recalls for this year, and to get rid of the pos before dumping anymore $$ into it.
