2006 MITSUBISHI RAIDER Engine And Engine Cooling Problems

GOT TRUCK MAY 2007 FROM A TOYOTA DEALER WITH 15K MILES AFTER DRIVING IT FOR A DAY WITH NO PROBLEMS. AFTER PAPERS WERE SIGNED, I STARTED THE ENGINE AND THE CHECK ENGINE LIGHT WAS ON. THE TOYOTA DEALERSHIP TOLD ME TO TAKE IT TO A MITSUBISHI DEALERSHIP SINCE IT WAS STILL UNDER WARRANTY. THE ENGINE RAN FINE. THE FOLLOWING DAY THE CHECK ENGINE LIGHT WAS NO LONGER ON. THE MITSUBISHI DEALERSHIP SAID IT MAY HAVE BEEN CAUSED BY THE GAS CAP BEING LOOSENED BY THE TOYOTA DEALERSHIP WHEN THEY FILLED THE GAS TANK AT THE TIME OF PURCHASE. SHORTLY AFTERWARD, THE CHECK ENGINE LIGHT CAME ON WHILE DRIVING 35-40 MPH AND IMMEDIATELY RAN WITH A ROUGH IDLE AND BUCKED WHEN ACCELERATING. THE FOLLOWING MORNING WITH LIGHT STILL ON, BUT NO ROUGH IDLE OR BUCKING, MITSUBISHI DEALERSHIP TESTS DETERMINED IT WAS THE #2 SPARK PLUG, WHICH THEY CORRECTED. SEVERAL DAYS LATER...

I HAD JUST PURCHASED THIS VEHICLE CASH ON FRIDAY, JULY 7, 2006. IT HAD 27 MILES WHEN PURCHASED. ON FRIDAY, JULY 14, 2006, I WAS DRIVING ON A 2 LANE ROAD ON MILITARY BASE IN SAN ANTONIO WHEN THE VEHICLE SHUT OFF AS I WAS MAKING A RIGHT TURN. THE VEHICLE WOULD NOT START. EVERYTHING ELSE WORKED IN THE VEHICLE EXCEPT START. I AM CURRENTLY STATIONED AT THE ABOVE POST FOR 3 MONTHS WHILE IN TRAINING AND PURCHASED THIS VEHICLE AT A LOCAL CAR DEALER. TRIED CALLING THE SALES CONSULTANT WHO SOLD US THE VEHICLE AT HER CELL, WHICH SHE GAVE MY WIFE WHERE I PURCHASED THE VEHICLE, NO REPLY, CALLED THE DEALERSHIP, THEY GAVE ME THEIR CUSTOMER SERVICE WHICH GAVE ME THE WRONG NUMBER TO CALL. THEY GAVE ME A SEX CALL NUMBER. I CALLED THE DEALERSHIP AGAIN AND THEIR RECEPTIONIST GAVE ME A PHONE NUMBER WHICH TURNED OUT...
