NHTSA Complaint #10643439 — 2004 CHEVROLET SUBURBAN

AT FIRST I GOT A CHECK ENGINE LIGHT ON WITH CODE P0430, O2 SENSOR LOWER BANK 2, THEN BANK 1. REPLACED THOSE TWO WORK FOR A WEEK THEN RPM AND SPEEDOMETER GAUGE FLUCTUATE UP AND DOWN. I DROVE HOME FROM THE AIRPORT ONE NIGHT AND ALL GAUGE READING WENT ALL THE WAY UP. I WAS TRAVELING ON AN INTERSTATE WITH A SPEED LIMITED OF 55MPH AND THE READING IN MY CAR WAS OVER 120MPH. TOOK TO IN SHOP, SHOP RECOMMEND I NEED SPEEDOMETER SENSOR REPLACED. REPLACED THAT, NOW ALL THE INSTRUMENT GAUGE JUMP UP AND DOWN. SOMETIME ALL THE WAY FULL SOMETIME ALL THE WAY DOWN. FINALLY GOT TIRE OF TRYING TO FIX IT MYSELF AND TOOK THE CAR TO THE DEALER AND THEY FOUND OUT IT WAS A BAD DASH INSTRUMENT AND BAD CATYLETE-CONVETER. THANKS TO CHEVY IT COST ME HEADACHE, GUESSING TIME, GIVING FALSE READING AND MOST OF ALL THOUSANDS OF DOLLARS TO GET IT FIX RIGHT. *TR
