How long has your 1999 Jeep Grand Cherokee had this problem?
RepairPal Certified shops can diagnose and repair your 1999 Jeep Grand Cherokee. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
There are too many variable here to give you an accurate diagnoisis without a hands on inspection. I appreciate the trouble code but considering you have already replaced parts, its best to bring it to a shop for a complete diagnosis. I'd hate to see you throw anymore money away on guessing.
