- Problem Abstract: Buzzing Sound
- Year: 1997
- Model: GTP
- Applicable Options: B4S
- Solution: Dealer consulted
Pontiac and was told to install foam between fuel line attachment points
and the floor pan. Apparently, the pulses from the higher pressure
injetcors used in the SC version were echoing the pulse back down the
fuel lines and causing the noise. The problem was greatly alleviated but
not totally eliminated by this.
