If you are backfiring through the TB, you have a timing issue or a throttle body position sensor that is bad. Test the sensor first then worry about timing if the sensor is okay https://www.gmforum.com/t279319/

forgot to mention can the TP sensor cause low RPM upshifts.. e.g cruising or climbing speed slowly it upshifts and wont downshift unless i let of the gas
