FPR? Fuel Pressure Regulator?

Is that the same as the Fuel Injection Pressure sensor?

If you don't need it today, Rock Auto is $10 cheaper. There is shipping, but no sales tax. They ship fast.

the bosh is supposed to be OEM, where the motor craft is oe replacement

I cleaned the MAF and TB today. Car idles much better and my fwy mpg is around 35 (city still ~26) This heavily suggests FPR

Mine is about due for some attention. I'll pay attention to the fuel system and see if I can get the mpg back up.

I'm throwing two codes now that are not displayed on the dash, but readable in the fixd product. car seems to drive fine, looking around with ppl who have these codes in the past - the codes seem to disable the automobile

p1000 -obd sys readiness not complete
p0a0a high voltage (transmission)

changed the fuel pressor sensor/ regulator and code cleared. car has a lot more power on the low end and gets better fuel performance in the city
