1995 Buick Riviera Q&A
1995 Buick Riviera Question: questions on codes
recently cars computer was read and several codes spit out. The first thing that showed was Quad Driver Failure followed by 101 mass air flow censor, 131 o2 cesor, 1670 Quad driver modular, 626 vets failure(alarm?) and finally 171 which is gas is lean I guess this one goes along with the o2 code. Car is running really rough idling high, lack of electrical power with acceration and making a horrible sounding noise when accerating. Need help!!!! any direction would be appreciated! - Rivibitch
If you have a Quad Driver error this is a computer or an output device problem It could be your Computer driver failed or the device it is driving is shorted. You need to determine this problem first. then we can tackle the rest. Good Luck! - dandd
