What would cause a 2003 p71 crown vic to run rich? Maf sensor cleaned new air filter... Also speedo worked even with a P0722 code and after I put new output sensor it stopped working altogether 😒... Car drives fine other than that. O2 sensors went bad?

For the P0172 and 0175 codes, take a read here--> http://troubleshootmyvehicle.com/for...d-p0175-page-1
For the P0722- •Faulty Speed Sensor
•Speed Sensor harness is open or shorted
•Speed Sensor circuit poor electrical connectionThese are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test. -
Figured it out 😊 needs a fuel pump... Low pressure.... 20 psi max... Injectors are almost continually open it order for car to run. Very Lean at WOT... Misfires at all cylinders at WOT. Which pump to buy? Motorcraft?

Last fuel pump I bought was a name brand from the local parts store. Lifetime warranty sealed the deal. Not that you want to do the job twice, or three times, but generally a brand name pump with a lifetime warranty will be decent.1990 Country Squire - weekend cruiser, next project
