Question about 1994 Ford Crown Victoria
At first I had a 172 code on O2 sensor, so I changed it. I was losing power going uphill and it runs/idles bad until it gets warmed up and then it runs better.
TP low (possibly grounded or open circuit) - TPS
that suggested it's not really the sensor itself is bad, but a wiring problem!
gotta trace and make sure the ground circuit and or wiring to that sensor is not broken
as for the other 3 digit code, no idea as well. reset the ecu/ecm and read the flashes again
