I had these symptoms when my car was in limp mode from a broken ABS module, on a manual transmission car. Braking and clutch-in to a stop, the DRL lights would cut and my engine would almost stall then kick back up.

Basically, if your car has a trouble code it will probably drive like shit and this is by design.

Can you make us a video showing the RPM dip when braking to a stop? Just for further documentation of the symptom for others who might have the issue. Thanks.

Googling P0171/P117B brings up a lot of results on this site. Fixes ranged from replacing flex pipes and fixing exhaust leaks, to replacing bad batteries.
