i put a new fuel sender in, new plugs and coils, cleaned the throttle body, and changed the injectors, swapped out the MAF, and it still runs terrible at idle and bogs and stalls when i give it any gas. its UN-driveable that's how bad it is. the only code i get is P0543 for EVAP pressure circuit voltage high. im wondering if its the fuel pressure sensor (FTP) or a charcoal canister/ purge valve issue. im at a loss. im gonna pop off the O2 to see if the CAT is clogged and to see if the O2 is dirty. maybe pop the valve cover to see if it jumped time, the motor has 234610 miles on it so its possible, all highway miles. apparently they burn valves sometimes so i was gonna do a leak down test but i dont wanna break a plug, that will be among the last ditch efforts. any suggestions anyone? shes got the 2.0 duratec

 

anybody there?

 

i can post a video of it running and stalling if needed

 

help please

 

nobody?? damn

 

If you can post the video, please do, thanks.

 

thank you, i will do that tomorrow without a doubt

 

1) If everytime it stalls you can restart it right up, what I'd do, buy only Motorcraft brand MAF on Amazon (with free return). Additionally, disconnect the electrical connector of your MAF and just drive, you should get very rough idling still but does it stall again?
2) Run a cycle of Berryman 2611 for any non-diesel cars, it will help more significantly on direction injection than port injection engine, no harm no risk.

 

ive swapped my MAF with a NOS i had laying around, unplugged it too, van is undriveable. it seems to make little to no difference
