“WHEN I USE THE CRUISE CONTROL AND THEN TURN IT OFF I CAN'T SEEM TO PUSH MY GAS PEDAL WHEN YOU ARE DRIVING THE VEHICLE.

I KEEP HAVING PROBLEMS WITH SMOKE COMING FROM ON TOP OF THE STEERING COLUMN LIKE SOMETHING IS BURNING WHEN YOU ARE DRIVING, NOW I HAVE ELECTRICAL PROBLEMS TO WHERE MY HORN WILL NOT WORK ANYMORE. I KEEP HAVING PROBLEMS WITH THE FRONT FRAME OF THE SUV. THE FRAME SOUNDS AND FEELS LIKE IT IS GOING TO FALL APART AND IT DOESN'T MATTER IF YOU ARE DRIVING OR STATIONARY.

SOME OF THE ORIGINAL THROTTLE BODIES INSTALLED ALLOWED A GAP BETWEEN THE PLATE AND BORE TO BE BUILT TOO NARROW.
