Have you had the transmission checked out? It sounds like it may be a problem with the torque converter.

SOURCE: bad stumble on acceleration pops through t- body.

Sounds like the fuel pressure regulator. Could also be that the timing jumped. But I'm leaning towards the pressure regulator. Hope that I could help. Best wishes.

It could be a lot of things, check the gas cap, vacuum leak, IAC, may need a tune-up ( check plugs, wires, air filter), seizing pulley, timing issue (check CKP sensor and CMP sensor), sticking valves, misfire, Fuel line pressure, or an issue with CAT or muffler.Good luck.

SOURCE: My 2004 Ford Expedition 4.6l has a rough idle and

well i'm sorry that you got the miss information here on fixya. because all internal combustion engines need a pcv valve to operate properly.

now the information you got first is correct and pcv valve can set false codes like o2's and lean bank conditions also can cause you vechile to run or idle rough.

no there are a few different styles pcv valves and some times don't look like your convetional pcv. some are heated in different ways either by coolant ( witch look like a conventioanl pcv but with a coolant tube around them) then electricaly heated and they don't look like them at all. but one thing that has to stay the same is the pcv valve has to ventilate the crank case and will be found somewhere on or near the valve cover because it is the easiest and most accessible point of the engines crank case area. so i would look for that and usally on that vechile it is on the passanger side valve cover in the middle.

with that said and seeing you did all those repairs i would go right for that as my next step. but there is other thing that cold cause this issue like leaky injectors and is almost more likely becuase of the o2 sensor code and backfire. do you have the code # so i can look it up and best assist you?

see vechiles are hard to fix over the computer as i am trying so if you have any more question/info about this issue please ask and i will be glad to help.

SOURCE: 2001 Ford Explorer idles rough when at a stop in

sounds like a vacuum intake leak..check a those little tubes for cracks and security. also check your transmission levels, this will sometimes cause a surging problem while driving..if all this checks good then it might be dirty or clogged injectors..purchase a can of Sea Foam from Autozone $10 pour in 1/2 can to half tank of gas and drive around for thirty minutes..highway driving preferred, and see if that will clean up the fuel system.Can i get some feedback, thanks

My expedition is a 5.4 two wheel drive eddie bauer the problem i "m having with it is that it started to waste more gas now. I get only ten miles to the gallon and before i would get about twelve...

The tune-up is a Fred Flintstone term,
meaning you got spark plugs or payed
for them and got nothing

You need new spark plugs
You need 2 new front O2 Sensors, if you
have 100,000 miles on them
You need the MAF Sensor Cleaned
A Clean Air filter
Correct fuel pressure
A properly working TPS Sensor
(throttle position sensor)
And other items.

See if you have all that done, and get back
I will evaluate your issues.

Do you have check lights on the dash
If so give us the codees

Some thing you should do also is change the fuel filter and check the air filter(if dirty,replace it) You can clean the throttle body also, you have to open up the plates and clean behind it as much as possible(use a tooth brush). I have done this to cars and it's better than the tune up they just got.

Your good
I would still remember, that all ford COP Coils have issues,from 1998 thru today
The Coolant Temp Sensor, should put it into closed loop, after it warms up---then the O2 Sensors can do their thing. That's one item
O2 Sensors slow to swing--maybe,need to test
Converter partially blocked-a bit of a stretch, but don't rule out.
I would buy one new coil, and walk it down from cyl to cyl,tough on that engine,but I put my money there

1999 Expedition - when in idle the speedometer and RPM needles occasionally go wild... any advise_

when was the car last serviced? if recently serviced what service did the garage do? servicing the car at 20,000 km involves changing spark plugs/ clean or change air filter, fuel filter/ engine oil filter in some case it alson involves cleaning the throttle body and cleaning injectors.depends on your climate and driving condition, your car might be having a faulty airflow meter or faulty idle speed control sensor, have those two checked or cleaned then if problem still the same have your car checked by a code reader to pinpoint the problem.

96 Ford Explorer is studdering (misfiring) when going up hills

I have the same exact problem that just started immediately AFTER I got a tranny service where they changed the Trans Fluid, Trans Filter, Fuel Filter. Took it back and they say nothing is wrong with it. Took it to the dealer thinking I could get some REAL answers... they just told me to replace spark plugs, wiring & coil, for $900. Only studders when quickly accelerating above 40mph. I've check other forums, they say to clean the Mass Air Flow sensor. Haven't tried it yet. This seems the easiest before replacing spark plugs. Any other suggestions anyone?? Please.....
