I recently had an issue with what I'm assuming is the low fuel pressure sensor, this is based on other tread on this forum. My the car would stall and/or loose throttle response and throw codes. Long story short, I changed the sensor and that seems to have solved the issue so far (changed the sensor 2 days ago) but I was thinking on changing the fuel filter just to be safe. Car is out of warranty so I'm trying to solve the issue myself.
