I HAVE A '05 MIDNIGHT JUST HIT 8200 MILES ON IT. YESTERDAY I WAS ON MY WAY HOME CRUISING AT ABOUT 80 MPH /3K ON THE TACH. I EXPERIENCED A COUPLE OF HESITATIONS AND THE TACH WOULD JUMP UP IN RPM. I SLOWED DOWN A BIT AND THE PROBLEM WENT AWAY. THIS MORNING COMING INTO WORK I WAS CRUISING DOWN THE FREEWAY AGAIN AT 80 WHEN IT HAPPENED AGAIN, THIS TIME, I THOUGH IT WAS POPPING, HESITATING THE TACH WAS JUMPING AROUND AND THE CHECK ENGINE LIGHT WAS FLASHING ON AND OFF. I WAS ABLE TO SLOW TO 70 /2500 RPM AND IT WENT AWAY. BUT AS SOON AS I WOULD TAKE IT BACK UP TO 80 IT WOULD HAPPEN AGAIN. *JB
