Car drives great…until it doesn’t.

Initial-Diver-5590B to Mechanic Advice@gearhead.town · 1 year ago

Here’s what we’ve had changed out with this problem already and I’m tired of mechanics just throwing parts at it hoping it fixes it: New plugs New coils New injectors New fuel rail line sensor

Car will drive great until you get to 15ish miles then it asks like it’s not getting enough fuel and will hesitate unless you really press it and it will still hesitate. Then we get the following codes:

PO171 - System too lean bank 1 PO191 - Fuel Rail Pressure Sensor Range/Performance

I’m at my wits end. Car has 130k miles on it. Any help would be much appreciated.
