Question about 1999 Ford Expedition

Open Question

My 99 ford expedition 4.6L has code showing P01131, p01151, p0136

My vehicle sputters while driving. I recently replaced the IMTV, heater core, spark plugs and wires, pcv hose and valve, and the fuel filter. I am frustrated I have cleaned the throttle body and egr valve as well. the vehicle has power and switches gears well but it still sputters almost like a vibration on the acceleration pedal. Any ideas

No use what's in there, but have the engine de-carboned by a Ford dealer, or remove the octane adjust shorting bar located near the ignition module (retards timing 2 degrees), this will in most cases cure the issue unless there is allot of carbon in the cylinders. There are also methods of ing this de-carbon procedure at home, check on the internet for tips.

first check the fuel pump relay under the hood on the drivers side and if it is good it could very possible be the fuel pump

Check fuel pressure. Could be fuel pump witch is in the tank and replace the TFI module located under the distributor.

SOURCE: 99 ford expedition 4.6 misses / egr? vacuum?

it's getting to much egr the egr has gone bad and needs replaced.
the diaphragm in the egr is leaking, and default position for air is when you hit 3000 rpm you don't have enough vacuum.

When you know the symptom who needs codes?And if there was a code it probable say lean bank 02. why simple you have a misfire. the smell rich exhaust the shake and sputter in drive. 2 causes the Expedition suffer from ,An open EGR valve.If you can change a fuel filter and change a spark plug you can test this. when the engine is running and misfire at idle and the vehicle is warmed up and at operating temperature. Turn off engine. Go to the EGR is it hot to touch. because if it is it open and this the the culprit.Another misfrie is from COP (coil on plug.)When you change the spark plug where any of the spark boot torn or worn that spark can go through. Or even a faulty COP will do this .To find it you have the engine running and lift one COP out of the cylinder and listen for a engine drop if the engine RPM drop the COP is good if no change in engine the COP is bad. By the way 600rpm in drive is low

Not sure if it is the fuel pump, but when I start my 99 ford taurus for the first time of the day, it acts like it is not getting enough fuel and doesn't want to run smoothly. It also has been popping and...

Check the spark plugs? Even with platinum plug gaps widen over time.
Check the thermostat and see if you are warming up OK. My 2000 had plugged water lines at the manifold/heater core bypass lines at the firewall.
You should have a code - since the rough running. It may not be the problem but show you where to go to solve it.

P0136, P1131, and P1151 codes on Ford Expedition 2000 4.6L

Your auto has four O2 sensors. Two upstream and two downstream; With two banks. Bank 1, sensor 1...and bank 2, sensor 1 are the two upstream (exhaust manifold before the catalytic). Bank 1, sensor 2 and bank 2, sensor 2 (other side of catalytic)

Code 1131= upstream; bank 1..sensor 1
Code 1151= upstream; bank 2..sensor 1
Code P0136 (generic code) bank 1..sensor 2 (questionable)

I wouldn't spend the money to purchase 3 sensors. Highly unlikely all three are bad; Cost is about $40/ ea.
Since there isn't a code for the cat's themselves, I would suspect the O2 circuit is malfunctioning. The rough idle is another clue.

Take an ohmmeter set it on X10 scale and measure the resistance from engine to body and body to negative post on battery terminal. You should read zero ohms (full needle deflection). If you do go buy two upstream O2 sensors. If you read
open or a high resistance run two straps from eng. to body...and body to neg.batt. post.

Noticed smoke coming out from the a/c vents and along side the front windshield, fogging up the window. The service engine light is on, but that has been on for sometime, then it went off last week, and is...

First off, God bless you for stepping up for that baby!
OK about the vehicle... Generally when a heater core goes bad, the symptoms of a white smoke occur from the vents. Another symptom is a sweet smell from the antifreeze, possibly dampness on the passenger carpet, dryness in the back of your throat... ha.
Sorry... heater cores aint cheap... mostly labor entensive. You could continue to drive trhe vehicle until you are ready for repair or whatever you decide to do. You'll just have to put up with the symptoms till you do, and you won't have much luck defrosting.
The engine code shouldn't pick this up... that's a different animal.
Hope this helps... Good luck!

When I turn the key on in my 99 Expedition Guages go to maximum

probably when heater core replaced instrument cluster was damaged. check for broken wires or loose connections. on newer vehicles sometimes if you disconnect the instrument cluster you have to reprogram it with a scan tool for the car to recognize it.

Diagnostic Codes p0171 bank 1, and p0174 bank 2 (too lean)

Those codes are for the oxygen sensors, lean fuel mixture on both banks. Change them, problem with stalling and rough idle should go away.
