Here we go.... just pulled out our service ticket:

Soooo interesting, I had never looked at these before:

So on 1/10/2005 we took the Vue in, and they did the following:
date: 1/10/2005
"CUSTOMER STATES THE SES LIGHT IS ON"
CAUSE: UNKNOWN
TECH COMM: SES LIGHT IS ON. FOUND FUEL TRIM LEAN CODE P0171 & P0174. RETORQUE INTAKE VACUUM CHAMBER BOLTS AND INSTALL VACUUM CHAMBER SPRINGS PER BULLETIN02/06/01/016A

REPAIR 1: INLET AIR CONTROL VACUUM RESERVOIR - REPLACE


Then, evidently it came back on a week later:

date 1/17/2005:

LINE1: "CUSTOMER STATES THE SES LIGHT IS ON"
CAUSE: OPEN
TECH COMM: SES LIGHT IS ON.
FOUND CODE P0171 FUEL TRIM LEAN B1 CODE P0174
FOUDN MASS AIR FLOW SENSOR FAILED REPLACED MAF SENSOR


...

The problem NEVER came back..

There's my experience. Good luck!

I have a 01 yukon denali that has hard starting and when I get to under a quarter tank it stalls out like I have no gas. I can eventually get it to start back up and I bring right to the gas station? P0174...


Hey jessica, from what you describe it sounds like a fuel pressure problem. A vehicle can have "weak" fuel pressure & may still be drivable but will not perform well on a hard acceleration. First get the fuel pressure checked and PLEASE go to someone who will use a fuel pressure gauge not stick a screwdriver in the test port and see if fuel sprays out! I believe the fuel pressure spec. for this vehicle is 55-60 psi with the key on. The codes po171,174 indicate "both banks lean" which could be caused by a lack of fuel pressure. These codes can be caused by a M.A.F. sensor problem (Mass Air Flow sensor). Common problems with M.A.F. sensors - they can get dirty and not work properly. I still highly recommend the fuel pressure test first! If it lacks pressure you know you have a bad pump. If the vehicle has a replacable fuel filter this needs to be checked & or replaced then re-check fuel pressure. If fuel pressure is OK then check for problems with the M.A.F. ( Dirty, Air leaks between sensor & engine throttle body, defective sensor) Hope this helps!

Losuing over drive lack of power hard starting must hold pedal to the floor


Does it start better after sitting overnight? Is it missing at all? Check engine light? Hard starting could be fuel pump, also lack of power could be lack of fuel. If it starts better after sitting overnight, could be block catalytic converter. That would also explain lack of power. If you have to hold gas pedal half way down trying to get speed would explain why it is not going into overdrive. Hope this gives you some direction.

Extreme hard start when warm. Keeps coming up


Have the cat checked,sounds like a restriction in the exhaust,or the return line to the tank is restricted,remove the fuel cap,and blow air back to the tank with compressed air,threw the return line,where the pressure regulator bypasses the fuel back to the fuel tank.

Winstar2003,codes po171,174


This usually caused by either a pcv tube elbow that is deteriorated or the upper intake gaskets and isolator bolts. If all the tubes are ok then I would replace the 6 upper intake o-rings and the isolator bolts. Use Ford parts only, they have been redesigned to keep the problem from occurring again.

Engine constantly stalls/lack of power.hard to start


Sounds like the fuel pump is failing. Take it to a local parts store that will read any codes. WRITE THE CODES DOWN if there are any, and report them back here for further help.
