OK HERE WE GO. SO THE ENGINE LIGHT IS ON AND HAS BEEN FOR A FEW WEEKS THEN THE (REDUCED ENGINE POWER LIGHT} COMES ON AND CAN ONLY GO 20 MILES AN HOUR. IF THE ENGINE LIGHT IS ON AND THE REDUCED ENGINE POWER IS NOT ON I CAN GO AS FAST OR SLOW AS THE SPEED LIMIT IS. BUT IF THE REDUCED ENGINE POWER LIGHT IS ON CAN ONLY GO 20 MILES PER HOUR...
I TOOK IT TO MY MECHANIC AND HE HOOKED IT UP TO BE TESTED ON THE ELECTRICAL SYSTEM MACHINE IT COST $85.50 TO DIAGNOSE IT AND IT CAME BACK AS P2318 ACCELERATOR PEDAL POSITION APP SENSOR. SO HE CLEANED AND RECHECKED IT AND IT WAS SAYING IT WAS GOOD.
NOW 2 WEEKS LATER I AM DRIVING WITH NO PROBLEMS UNTIL MOTHERS DAY. I DROVE TO MY DESTINATION JUST FINE BUT WHEN I LEFT IT WAS DARK AND COULD ONLY GO 20 MILES AN HOUR, AND THE READING ON MY DASH SAID REDUCED ENGINE POWER. SO THANK GOD I COULD TAKE A ROAD THAT WAS 30 MPH UNTIL I GOT HOME. NEXT DAY THE REDUCED ENGINE POWER LIGHT WAS OFF BUT THE ENGINE WAS ON AND I COULD DRIVE 70 MILES PER HOUR NO PROBLEM. THEN NEXT DAY THE REDUCED ENGINE POWER LIGHT CAME ON AN IT WOULD ONLY GO 20 MILES AN HOUR.
SO NOW I AM GOING TO GM CHEVY DEALER AND THEY ARE TELLING ME THAT IT COULD BE THE THROTTLE BODY AND OR THE PEDDLE SENSOR ETC.. REALLY SAD THEY ARE SAYING OVER 500 DOLLARS OR MORE TO FIX THIS .. GM NEEDS TO DO A RECALL AND FIX THIS PROBLEM
