HI,I JUST BROUGHT MY 3126 CAT MOTOR WITH 55,000 MILES IN TO THE DEALER TO HAVE IT DIAGNOSED ,,,BECAUSE OF LOW POWER AND POOR EXELLERATION... ALREADY CHANGED FILTERS ,OIL, FUEL PRESURE REG. FUEL ACUATION SENCORS. S0 THEY READ THE ECM TO MAKE SURE THE MILES WERE CORRECT
...NOW,THEY CLAIM THE ENGINE WAS HUNTING WHEN HOT I HAVE NEVER HEARD THAT FRAISE WHAT DOES THAT MEAN IS THAT THE SAME AS A MUFFLER BEARING? HA!,,,THEY ALSO SAY THAT THEY PERFORMED A CYL, BALANCE TEST CAN YOU TELL ME WHAT THAT IS??? THEY SAY # XXXXX CYL WAS ABNORMAL FROM THE BALANCE TEST I TOLD THEM I WANTED IT DIAGNOSED,,,I ALWAYS THOUGHT IT WAS CALLED A CONTRIBUTION TEST

Already Tried:
MANY THINGS WHAT TEST SHOULD BE PERFORMED IN ORDER TO DIAGNOSE MY MOTOR THERE ARE NO CODES PRESENT I AM SICK OF BEING JERKED AROUND FROM THE DEALERSO FAR 400.00 TO TELL ME THERE ARE NO CODES PRESENT WHICH I ALREADY KNEW AND A CYL BALANCE TEST GOD KNOWS WHAT THAT IS. CAN YOU PLEASE TELL ME WHICH TEST SHOULD BE DONE TO FIND OUT WHY MY MOTOR WON,T GO OVER 40 MPH UP HILL EMPTY?? NO LOAD THANK YOU PHIL
