2004 KIA AMANTI Power Train Problems

WHEN I START MY CAR, THE RPM ACCELERATES HIGH AS IT WILL GO. VERY ANNOYING AND LOUD. IT DOES THIS MOST OF THE TIME SOME TIMES WHEN I COME TO A STOP LIGHT AND PROCEED FORWARD, THE CAR JERKS FORWARD AS I ACCELERATE. *TR

KIA AMANTI LOSING POWER WHILE DRIVING OR LOSING POWER THEN ACCELERATING OUT OF CONTROL AND KIA SEEMS NOT TO BE ABLE TO FIX THE PROBLEM. *TR

MY CHECK ENGINE LIGHT COMES ON AND MY CAR LOSES POWER FAST NO MATTER WHAT SPEED I AM GOING. I PUT MY FOOT ON THE GAS AND THE RPM'S GO UP AND I AM ONLY ABLE TO DRIVE AT A SPEED OF 20MPH. AT TIMES MY CAR WILL DRIVE AT A NORMAL SPEED AND THE CHECK ENGINE LIGHT WILL BE ON .ITS VERY STRANGE. I'VE TAKEN IT TO THE DEALER AND THEY SAID THAT IT NEEDED A NEW CATALYTIC CONVERTER. IT WAS REPLACED UNDER WARRANTY. ONE WEEK LATER THE SAME SYMPTOMS AND ANOTHER OUT OF POCKET EXPENSE OF OVER $1,000.00 AND ANOTHER PART. THE PROBLEM STILL EXISTS MONTHS LATER. EACH TIME WITH A DIFFERENT DIAGNOSIS BY THE DEALER. MY MECHANIC DIAGNOSED THE PROBLEM WHEN IT FIRST HAPPENED WITH HIS METER AND IT READ ELECTRONIC THROTTLE BODY. I TOLD THIS TO THE DEALER MONTHS AGO AND THOUSANDS OF DOLLARS AGO. *TR

THE VEHICLE SURGES WHILE ACCELERATING. THE PROBLEM OCCURS SPORADICALLY BUT HAS DONE IT CONSISTENTLY FOR OVER 5 YEARS. EVERY TIME I TAKE IT TO THE DEALER THEY CAN'T FIND ANYTHING WRONG AND NOTHING IS DONE. THIS VEHICLE HAS AN ELECTRONIC THROTTLE. *TR
