2003 TOYOTA 4RUNNER Engine And Engine Coolingexhaust System Problems

TOYOTA 4-RUNNER 2003 SIX CYLINDER. EXCESSIVE SULFUR DIOXIDE ODOR. NO EVENTS LEADING UP TO FAILURE. SPORADIC. DEALERSHIPS GAVE ME A HARD TIME, WANTED $150.00 TO RUN TEST EVEN THOUGH TOYOTA HEADQUARTERS INFORMED ME THAT THE DEALER SHOULD JUST REPLACE PARTS, SO I NEVER HAVE HAD IT FIXED BUT I AM CONCERNED. I CHANGED GAS STATIONS NUMEROUS TIMES AND STILL RECEIVE THE ODOR. ODOR COMES AND GOES AND CAN BE STRONG AT TIMES ESPECIALLY IN COLD MONTHS. CONCERNS ARE THAT IT WILL BECOME WORSE AND THE SMELL IS TOXIC. *TR

2003 TOYOTA 4RUNNER SPORT ED, 6 CYL.- AT 100,400 MILES, BOTH MY CATALYTIC CONVERTERS WENT OUT. ALSO THE CHECK ENGINE LIGHT GOES ON WHICH DISENGAGES THE VEHICLE SKID CONTROL, SO I HEAR. REPAIRS ARE COSTLY. CAN'T SMOG CAR ON THE FIRST TIME CAR EVER NEEDS TO GET SMOGGED. SEEMS LIKE A RECALL ISSUE TO ME? *TR

I OWN A 2003 TOYOTA 4RUNNER AND HAVE BEEN EXPERIENCING A SULFUR/ROTTEN EGG SMELL SINCE I GOT IT. IT IS INTERMITTENT AND SEEMS TO OCCUR MOST FREQUENTLY UPON ACCELERATION. THERE HAVE BEEN TIMES WHILE DRIVING THAT I GET VERY DIZZY. AFTER RESEARCHING I FOUND THERE A QUITE A FEW COMPLAINTS ABOUT THIS VERY PROBLEM. IT SEEMS ALONG WITH THE SULFUR DIOXIDE THERE IS CARBON MONOXIDE INSIDE THE CABIN, REGARDLESS IF THE WINDOWS ARE UP OR DOWN. TOYOTA'S RESPONSE IS THAT THIS IS DUE TO BAD GAS. I LIKE MY 4RUNNER BUT THERE IS NO WAY I CAN DRIVE IT KNOWING THAT NOT ONLY ME, BUT MY SON ALSO ARE BEING POISONED. TOYOTA MUST BE HELD ACCOUNTABLE AND FIX THIS IMMEDIATELY BEFORE SOMEONE GETS SERIOUSLY HURT!!!! *TR

FOUL SMELLING EXHAUST - AMMONIA SMELL - VERY STRONG ON ACCELERATIONS UPHILL OR FREEWAY ON RAMPS. *JB
