MY 1994 JEEP GRAND CHEROKEE HAS FUEL LINE PROBLEMS THAT KNOW ONE CAN SEEM TO FIX. THERE AREN'T ANY LEAKS, HOWEVER, IT JERKS AND SLIPS INTO A NEUTRAL STATE FROM TIME TO TIME. FIRST I BEGAN TO ADD EXPENSIVE FUEL CLEANERS (DIDN'T WORK), THEN I HAD IT SERVICED BY 3 DIFFERENT MECHANICS WHO ALL PERFORMED FUEL EMISSION CLEANING. CURRENTLY, IT STILL SLIPS, THEN JERKS FORWARD WITH EXTREME FORCE-ONE TIME CAUSING AN ACCIDENT. NOW THE JEEP CANNOT STAY ON WHEN IT IS STARTED, IT COMES ON AND DROPS DEAD, I HAVE TO RACE THE ENGINE TO KEEP IT FROM SHUTTING BACK DOWN. IN 2001 I HAD A TRANSMISSION OVERHAUL THEREFORE IT CANNOT BE A TRANSMISSION PROBLEM. THE "COOLANT SENSOR IS BAD" SIGNAL STAYS ON THE COMPUTER, I WENT TO REPLACE IT, HOWEVER, JEEP EAGLE AND THE REST OF THE AUTOPARTS BUSINESSES HAVE A DIFFERENT MODEL SENSOR THAT DOESN'T APPEAR TO BE THE SAME AS THE ONE IN MY JEEP, THEIR REPLY IS "I DON'T KNOW WHY THEY LOOK DIFFERENT, IT MUST BE THE WRONG ONE." THE REAR LAMP FAILURE LIGHT IS ALSO ON YET THERE ARE NO BAD LIGHTS IN THE REAR, AND I CHECKED EVERY LAST ONE OF THEM. DURING THE SUMMER THERE IS WATER LEAKING FROM UNDER THE DASH BOARD ONTO DRIVER AND THE PASSENGERS FEET. WHAT I WOULD LIKE TO KNOW IS WHETHER THESE ISSUES ARE ONLY MY PROBLEM OR THE MANUFACTURER? *LA
