2004 Kia Amanti Engine Problems

The 2004 Kia Amanti will accelerate on it's own. I have been in local traffic and it accelerates and de-accelerate like a run away horse. It will then drive normal. The check engine light comes on sometimes and goes back out. This last time the light came on, I took to an electrical auto repair place. The computer read out said it needed a throttle body. I replaced it as suggested. The 2004 Kia Amanti attempts to accelerate on it's own and stops and drives normal again. The check engine light is on again. I would like to get what is perfect and right for the Kia to perform better and be safe. How do I do that?

AFTER GETTING HOME LAST NIGHT FROM MY SISTER IN LAW'S GENDER REVEAL, I SAW SMOKE COMING FROM UNDER THE BONNET SO I OPENED IT QUICKLY AND SAW A FIRE BLAZING BEHIND THE ENGINE....WHEN THE FIRE DEPARTMENT GOT THERE, THEY POINTED OUT TO ME THAT THE FIRE WAS ELECTRICAL..... I NEED SOME FORM OF COMPENSATION FROM THE COMPANY AS I AM NO LONGER ABLE TO DRIVE THE CAR AND ELECTRICAL ISSUES ARE WIDELY AFFILIATED WITH THIS PARTICULAR MODEL OF KIA CARS.

ON 6 SEPARATE OCCASIONS THE VEHICLE HAS SLOWED DOWN AND "CHUGGED" OUT OF THROTTLE POWER WHILE INITIALLY DRIVING AT SPEEDS OF ANYWHERE BETWEEN 35 AND 65 MPH. IF THE VEHICLE DOES MANAGE TO KEEP DRIVING, IT DOES SO IN A VERY JERKY WAY, ALMOST LIKE SOMEONE WHO DOES NOT KNOW HOW TO DRIVE STICK. I'VE FOUND THAT THE ONLY WAY AROUND THIS JERKING IS TO DRIVE THE VEHICLE IN SPORT-SHIFT MODE IN A LOWER GEAR SO THAT THE RPMS STAY ABOVE 3000. SOMETIMES THE VEHICLE IS ENTIRELY UNRESPONSIVE WHEN THE GAS PEDAL IS PRESSED, WHICH (MULTIPLE TIMES) NEARLY PUT ME IN A SEVERE CAR ACCIDENT ON BUSY I-95 IN BOTH FLORIDA AND PHILADELPHIA, PA. THE CHECK ENGINE LIGHT HAS ONLY EVER REMAINED ON ONCE, GIVING AN ERROR CODE P1614: "ENHANCED TRACTION SYSTEM ENGINE CONTROL MODULE MALFUNCTION." IN THE PAST, TURNING THE IGNITION OFF AND BACK ON IMMEDIATELY HAS FIXED THE ISSUE TWICE. OTHER TIMES THE VEHICLE NEEDED TO REMAIN OFF FOR AN EXTENDED PERIOD OF TIME BEFORE THE PROBLEM WOULD CLEAR UP. THE CHECK ENGINE LIGHT CAME ON ONLY 2 OF THE 6 TIMES THE PROBLEM HAS OCCURRED. THE FIRST TIME IT CAME ON, IT DID NOT REMAIN ON ALTHOUGH THE PROBLEM PERSISTED. CURRENTLY, THE CHECK ENGINE LIGHT REMAINS ON ALTHOUGH THE VEHICLE HAS BEEN RUNNING SMOOTHLY SINCE THE MOST RECENT OCCURRENCE OF THIS ISSUE WHICH HAPPENED ON JANUARY 8, 2015. I DO BELIEVE THE PROBLEM MAY BE LINKED TO THE FUEL INJECTORS. I FIND THAT ADDING FUEL SYSTEM CLEANER TO A FULL TANK OF GAS EVERY OTHER WEEK HELPS ME AVOID HAVING THIS 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

I WAS ON THE HIGHWAY GOING OUT OF TOWN AND HAD THE CRUISE CONTROL SET LIKE I NORMALLY DO WHEN ALL OF A SUDDEN MY CAR DRASTICALLY LOST SPEED FROM 70MPH TO 45MPH ON A VERY BUSY HIGHWAY. I HAD TO SLOWLY MOVE OVER TO THE FAR LANE IN ORDER TO MAKE IT TO A SAFE PLACE TO PULL OVER. I THEN PULLED OVER SHUT THE CAR OFF FOR ABOUT 20 MINS AND TRIED TO COME BACK HOME AND ONCE AGAIN GOT ON THE HIGHWAY WHEN ONCE AGAIN I LOST POWER EVEN THO I'M PRESSING THE GAS ALL THE WAY DOWN TO THE FLOOR AND ITS NOT EVEN TRYING TO GAIN POWER AT ALL. I ALMOST GOT INTO 2 ACCIDENTS ON THE WAY HOME BECAUSE OF THE LOSS OF POWER. I HAVE SEEN A LOT OF COMPLAINTS ON THIS WEBSITE ABOUT THE SAME RECURRING PROBLEMS WITH OTHER KIA AMANTI OWNERS AND THIS PROBLEM NEEDS TO BE FIXED. THIS IS MY ONLY VEHICLE AND I'M SCARED TO DRIVE IT. PLEASE CAN SOMEONE GIVE ME SOME ANSWERS!!! *TR

I WAS SLOWING DOWN TO A RED LIGHT AND THE CHECK ENGINE LIGHT CAME ON AND THE CAR DIED. I TURNED THE KEY SO I COULD BEGIN TO TRY TO START THE VEHICLE AND I NOTICED THE RPM'S START REVVING UP AND ITS TRYING TO OVER-ACCELERATE WHEN I PUT IT IN DRIVE. I MANAGED TO GET IT TO A SAFE SPOT BUT I WAS 100% WORRIED IT WAS GOING TO CAUSE AN ACCIDENT OR ACCELERATE OUT OF CONTROL. IT SOUNDS VERY IF NOT EXACTLY SIMILAR TO A LOT OF THE OTHER COMPLAINTS. NO CODES COME UP FOR THIS ISSUE AND IT IS SERIOUS. *TR

AFTER PULLING THE CAR FORWARD OUT OF THE GARAGE IN THE MORNING AND WHILE STOPPED TO WAIT FOR THE GARAGE DOOR TO CLOSE (BRAKE APPLIED, IN GEAR), THE VEHICLE ATTEMPTS TO BURST-LURCH FORWARD (NOT TOUCHING GAS PEDAL). THIS SEEMS TO HAPPEN YEAR-ROUND. THE DEALERSHIP CANNOT RE-PRODUCE THE PROBLEM, BUT ALSO HASN'T KEPT THE VEHICLE OVERNIGHT FOR A COLD-START. HAVE HAD A COUPLE OF NEAR-COLLISIONS AT THE END OF MY DRIVEWAY. *TR

2004 KIA AMANTI - ON COLD STARTUP THE ENGINE SOMETIMES REVS AGGRESSIVELY WHEN PULLED INTO GEAR, CAUSING THE CAR TO LURCH FORWARD OR BACK IF THE BRAKE IS NOT FIRMLY APPLIED. IT IS A DANGEROUS SCENARIO. I'VE ASKED KIA TO LOOK AT THE PROBLEM AND THEY'VE SAID THEY CANNOT IDENTIFY THE CAUSE AND HAVE NO KNOWLEDGE OF IT. *TR

I BOUGHT A BRAND NEW 2004 KIA AMANTI. AS I APPROACHED 30,000 MILES THE ENGINE WOULD PERIODICALLY LOSE POWER WHILE IN OPERATION, THEN RESTORE SECONDS LATER. I REPORTED THE INCIDENT TO MY DEALER. I WS TOLD THEY WOULD RESET THE FUEL INJECTION SYSTEM, AND THAT WOULD RESOLVE THE ISSUE. SINCE THEN THE ISSUE HAS SURFACED (3) TIMES. TWO OF THE THREE TIMES ALMOST LEAD TO A SERIOUS CRASH. DURING THESE PRECIOUS FEW SECONDS (3-5) THERE WAS ABSOLUTLEY NO ENGINE POWER AVAILABLE. I NOTICE IT IT SEEMED TO OCCUR WHEN REMOVING THE FOOT FROM THE GAS PEDAL, THEN REAPPLYING IT TO GAIN POWER. AT THIS POINT THE ENGINE JUST DROPPED OFF. IT WILL RESTORE AND RACE TO HIGH RPM SECONDS LATER. IT HAS GOTTEN TO THE POINT WHERE I WAS AFRAID OF DRIVING THE VEHICLE. IT WAS A CRAP SHOOT EVERYTIME YOU NEEDED TO MAKE A LEFT TURN ACROSS ON COMING TRAFFIC WHETHER OR NOT MY CAR WILL LOSE POWER. IT WAS NOT A STALL, NEEDED TO RESTART THE VEHICLE AFTERWARDS. THE VEHICLE RECOVERED ON ITS OWN.*AK

DEAR SIR: I AM THE OWNER OF A 2004 KIA AMANTI. THERE ARE 43,542 MILES ON THE ODOMETER. THE VEHICLE ENGINE RUNS FINE AND THEN WILL SUDDENLY GO INTO LUGGING AND MISFIRING AT VARIOUS SPEEDS CAUSING DOWN SHIFTING. WHEN I TURN THE ENGINE OFF AND LEAVE IT TO SET OVERNIGHT OR FOR MORE THAN EIGHT HOURS AT WORK, THE ENGINE LIGHT REMAINS ON BUT THE ENGINE RUNS FINE ONCE STARTED AGAIN. AFTER A FEW MORE STARTS THE ENGINE LIGHT GOES OFF. I TOOK IT TO THE DEALERSHIP AND TOLD THEM OF THE SYMPTOMS. THEY RAN TESTS AND SAID THEY COULD FIND NOTHING WRONG. THEY SAID BRING IT BACK WHEN IT DOES IT AGAIN. FINE, SO IT GOES INTO THE MISFIRING ON A WEEKEND AT NIGHT TRAVELING THE INTERSTATE. NO CHANCE TO JUST LEAVE THE ENGINE RUNNING FOR A DEALERSHIP THE NEXT DAY. NOW IT RUNS FINE AGAIN UNTIL ANOTHER INCONVENIENT SITUATION. PROBLEMATICALLY, THE ENGINE BEHAVIOR CREATES A DRIVING HAZARD AT HIGH AND LOW SPEEDS AND COULD EASILY CAUSE AN ACCIDENT. THIS IS A SERIOUS SAFETY ISSUE THAT NEEDS TO BE RESOLVED BY KIA, NOT BY ITS IGNORANT OR ILL TRAINED DEALER MECHANICS. ARE YOU FAMILIAR WITH THIS PROBLEM? IS IT THE COMPUTER MODULE THAT MAY HAVE A SHORT OR CRACK IN THE HOUSING? MISFIRING IS A TIMING ISSUE AND MOST SURELY GOES TO THE FIRING ORDER AND TIMING CONTROLLED BY THE ADVANCE MECHANISM AND THE MODULE. OR IS IT THE THROTTLE SYSTEM? OR EGR VALVE OR SOLENOIDS? DO AMERICANS NEED TO DIE BEFORE KIA COMES UP WITH AN ANSWER? I NEED TO GET THIS FIXED BEFORE MY WIFE WHO PANICS MAY HAVE A SERIOUS ACCIDENT. *JB
