1999 Ford Expedition EB 4WD 5.4L Sputter Shutter on Load Heavy Acceleration

Asked by Nov 03, 2016 at 11:07 AM about the 1999 Ford Expedition 4 Dr Eddie Bauer 4WD SUV

Question type: Maintenance & Repair

1999 Ford Expedition EB 4WD 5.4L 200K sputters and shutters under load
/ heavy acceleration, low or high RPM's. Normal driving 1/3 peddle and
under 2K RPM's NO sputter or shutter. Initially told misfire Bank 2
suggestion was to replace COP's and injector O-rings. Replaced all spark
plugs, COP's and injectors. Starts instantaneously now and more
responsive but still shutters and sputters under load. Suggestion to replace
TPS, MAF and fuel filter since it had 200K on it and nothing had been
replaced since new so I replaced all. Still shutters and sputters but now
notice it runs a little rough at idle and the exhaust smells weird not like gas
just something I've never smelled before. Suggestion of possible vac leak,
have sprayed carb cleaner, brake cleaner and starter fluid all around can't
fine anything, Starts immediately cold or hot, cold IAC has it at 980 RPM's
then settles to 600 RPM's. Never surges. Drove around for about an hour
trying to get it to throw a code P1132 and P1152, Sensor 1 for bank 1 & 2 ,
LACK OF H2OS11-NOT SWITCHING - RICH assuming this means LEAN
(no O2) condition from what i've read. Suggestion was test the fuel
pressure and regulator. 30 psi at the rail, 35 psi with new fuel filter engine
running. Removed vac hose from regulator jumps to 40 psi. Engine off,
ignition off, psi drops to 0 in a couple of minutes. Never holds pressure
once off. Q: shouldn't line hold pressure within 5psi when pump is off? Also,
Is the fuel pump working just not enough when fuel demand increases.

I suspect that you have a plugged up catalytic converter.

Would the plugged cat cause shutter and sputter condition or throw the code? This is the first time since all of the work has been done that the P1132 and 1152 showed up. I will perform vac and temp test today.

You may have a bad Oxygen sensor.

Mine did that and it was a coil pack

Thanks for all of the responses. Picked up a infrared thermometer to test the cat temp and I have ordered a Waekon 76562 Coil Over Plug Quick Probe with Variable Sensitivity to try and test the COP's since there is no live data from the PCM for cylinder specific misfires and no codes / cel has never flashed. Also, I am testing both upstream HO2's to rule them out using this http://troubleshootmyvehicle.com/ford/4.6L-5.4L/how-to-test-the- oxygen-sensors-1. I'll report results once complete. Thx
