2007 DODGE SPRINTER 2500 Engine And Engine Cooling Problems

2007 DODGE SPRINTER I HAVE HAD 3 OF THESE VANS THAT HAVE HAD THIER SWIREL VALVES (INTAKE MANIFOLD) GO BAD.WHEN THIS HAPPENS THE VAN HAS NO POWER AND IS UNSAFE TO DRIVE. I WAS TOLD BY THE DEALER THIS HAPPENS ALL THE TIME. *TR

I LEFT FOR VACATION OCTOBER 15, 2010 AND HAVE A LOSS OF POWER , CAN'T GO OVER 55MPH, WHICH IS GOOD FOR SAVING DIESEL FUEL BUT NOT FOR WANTING TO GET TO MY VACATION PLACE. THIS SPRINTER HAS ONLY 9,300 MILES ON IT. *TR

DRIVING FREEWAY AT 70MPH, ALL OF A SUDDEN THE ENGINE DOES WHAT SEEMS LIKE A STALL, QUICKLY DROPPING DOWN TO 35MPH AND CONTINUES TO SLOW DOWN AS WE MANEUVERED TO SIDE IF ROAD. THIS WAS VERY CLOSE TO CAUSING THE SEMI TRUCKS BEHIND US TO REAR-END US. WE PULLED OVER, DRIVING OFF THE FREEWAY AT 15MPH WITH HAZARDS ON. STOPPED AT A TRUCK STOP (I AM A FEMALE HERE, SO SAFETY WAS A CONCERN) AND PROCEEDED TO TALK TO INSURANCE COMPANY/TRY TO FIND A DODGE DEALERSHIP WHO ACTUALLY COULD "WORK" ON THESE SPECIFIC SPRINTER ENGINES. AFTER MUCH TROUBLE, END RESULT IS THE VEHICLE ENDS UP AT A CERTIFIED DODGE DEALERSHIP WHO IS VERY AWARE OF THIS COMMON PROBLEM AMONG SPRINTERS (DEALS WITH THIS SAME ISSUE CONSTANTLY). IT IS THE TURBO RESONATOR THAT IS A FAULTY PLASTIC PIECE THAT OFTEN AND FREQUENTLY BREAKS ON THESE VEHICLES. THE ONLY THING THE DEALERSHIP...
