If the vehicle is an manual transmission than it's safe to drive. Theres no risk of causing more damage to the car and safe, But if your vehicle is an automatic transmission than get it repair first don't take the chance.

P0171....-> this code is the Mass Air Flow Sensor ( MAF ) on the intake manifold. For this is not really a big of a deal cause mainly theres too much dirt in the sensor that just needs to be removed. Before buying a new one try to clean it with alcohol and air leaks on all hoses.

Check Engine Light Code P0974

Pontiac Vibe
for last few weeks my Vibe was occasionally shifting hard into neutral when at a stop, with a noticeable shake. It was not often enough to bring it in, but enough to be a little concerned. Two days ago, the check engine light came on while driving home. I took it to an auto part store and had them check the light and this code came up. However, since the light came on I have not had the downshifting issue so not sure what the heck is happening. Not looking forward to replacing another part since I just had my engine replaced last month.
