Hello..my husband's tuck does the same thing . Did you ever figure out what was wrong?
-
Without the full repair history report I can say it’s possible there is a rub in a wire or several. Also, has the ECU and TECU been replaced with test ones driven with no faults?
The control units can short out and you won’t know it’s a for sure fix unless dealer has a test one to drive unit several miles. Alternative is to replace both. -
For this original post the micro brake switch spring was the issue. Replace micro break switch and resolved loss of throttle at random times.
