2009 Chevrolet Equinox VEHICLE SPEED CONTROL,ENGINE

VEHICLE DISPLAYED WILL IN MOTION MERGING ON TO THE HIGHWAY. THAT WHEN YOU TAKE OFF A DELAY HAPPENS AT OVER 4000 RPMS OR AT ANYTIME YOU TRY TO GO OVER 4000RPMS. ITS LIKE THE ENGINE CUTS OFF OR LOSES ACCELERATION AN STAYS AT 40 MPH AND WILL NOT ACCELERATE UNTIL THE GAUGE FOR RPMS GOES BACK DOWN UNDER 4000 RPMS. THEN THE ENGINE WILL START TO ACCELERATE AGAIN LIKE A NORMAL VEHICLE UNTIL YOU TRY TO PICKUP SPEED OR ACCELERATE OVER 4000 RPMS.

ON OCTOBER 16, 2014, I WENT TO THE DEALER TO PICKUP MY VEHICLE STILL WITH NO ANSWERS TO WHY THE DASHBOARD MESSAGE IS READING: STABILITRAKING OFF, SERVICE TRACTION CONTROL, SERVICE STABILITRAKING AND ENGINE POWER IS REDUCED. THEN THE ENGINE SHUTS DOWN. AS I WAS PULLING OFF THE DEALERSHIP LOT, THE ENGINE LIGHT STARTING FLASHING RAPIDLY, VEHICLE BEGAN TO LOOSE POWER, IT WAS BACKFIRING AND SMELLED OF A FOUL ODOR. THE SALES MANAGER CAME OUTSIDE TO DRIVE THE VEHICLE AND THE VEHICLE CONTINUED TO LOOSE ENGINE POWER. BY THE TIME HE CAME BACK INSIDE TO SPEAK WITH US, HE STATED THAT HE COULD NO LONGER TURN THE VEHICLE ON. HE STATED THAT IT WOULD NOT TURNOVER AT ALL. I AM NOW AWAITING THE FINDINGS AND GRATEFUL TO GOD THAT PROBLEM HAPPENED AGAIN ON THE DEALER'S LOT AND NOT IN RUSH HOUR TRAFFIC. *TR

THE THROTTLE BODY WENT BAD IN MY CAR FOR THE 2ND TIME IN 3 YEARS. I HAD THE THROTTLE BODY REPLACED IN JANUARY OF 2011, AFTER ONLY OWNING THE CAR A MONTH. IT NOW NEEDS REPLACED AGAIN TODAY IN JANUARY OF 2014. I PRESS THE GAS PEDDLE AND CAR DOESN'T GO ANYWHERE, THEN ALL OF THE SUDDEN IT WILL TAKE OFF AND RUNS AS IF THE ENGINE IS BEING PUSHED AND PULLED. IT ALSO STALLED OUT ON ME ONCE WHILE DRIVING IT. THIS IS A SAFETY HAZARD WHEN SITTING IN THE MIDDLE OF AN INTERSECTION TO MAKE A LEFT TURN AND THE CAR WILL NOT GO FORWARD. *TR
