NHTSA Complaint #10403756 — 2001 CHEVROLET IMPALA

BOUGHT MY CHEVY 2001 IMPALA MAY 2010 AT 114,000 MILES. A WEEK LATER THE CHECK ENGINE LIGHT CAME ON FOR THE MASS AIR FLOW SENSOR. CAR RAN FINE, CHANGED THE MAF IN FEBRUARY 2011 AS THE CAR BEGAN TO CHUG AT STOP LIGHTS. A WEEK LATER THE CAR STALLED ON THE WAY HOME AFTER ABOUT AN HOUR OF DRIVING. HAD SPARK PLUGS, FILTERS, FLUIDS, TPS SENSOR (TWICE), CRANK SHAFT SENSOR AND IGNITION MODULE CHANGED. CAR IS NOW CHUGGING, STALLS OUT, AFTER STALLING THE TURN SIGNALS DO NOT WORK FOR A WHILE AND HAS TROUBLE CLIMBING TALL HILLS (DOES NOT ACCELERATE). THE CHECK ENGINE LIGHT COMES ON OCCASIONALLY AND IT READS THE TPS SENSOR IS BAD. CHECKED THE WIRES NEAR THE TPS SENSOR AND MAF SENSOR NOTING WHEN TOUCHING WIRES THE IDLE OF THE CAR INCREASES. COME TO FIND OUT THERE WAS A COMPARTMENT FIRE BEFORE I HAD BOUGHT THE CAR AND IT APPEARS SOME WIRES WERE SPLICED. IN PROCESS TO CHANGE THE WIRING HARNESS. UNSURE IF THIS WILL FIX THE PROBLEMS. *TR
