Question about Chrysler Pacifica
I have used some fuel injector cleaner
Check your fuel pump pressure. You should be above 50 psi. With the gauge hooked up, run the car, and see if the pressure drops.
That would be the first step

the owner probably rerouted the fuel line because like my 92 chrysler lebaron v6 3.0 the fuel lines keep seeming to come off and the clamps always break. I have replaced the clamps 5 times in a month and replaced filters 2 times in 2 months. The only thing i could think of is that your fuel is being cut off possibly because there is no filter to clean all the junk out. Try putting a fuel filter on and see if that will work

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

easy fix..o.k. a P0171 is a lean engine dtc..witch means wrong air fuel mixture..ideal is 14.1 yours is lean...witch means more air than fuel..check to see if there is a intake manifold leak..or vacuum leak.spray small amount of carb cleaner around intake manifold gaskets and see if engine smooths out if it does its a gasket also check for vacuum leaks around air filter rubber snorkle.and all vacuum leaks...if these check out ok...replace the 1st 02 sensor it also controls air and fuel and will cause this issue....as far as a P0442 thats your fuel evap system witch is un related to the first code make shure your fuel cap is tight and sealed...if so replace the evap vent control valve on the canister in the rear by the fuel tank..
