Have you changed your fuel filter? When is the last time you changed your sparkplugs? Have you had any codes on the computer? Heres what I would do. First change your sparkplugs. This is a 4-6 hour job. You have to unbolt the cop(coil on plug assembly). After you change the plugs your truck will run rough. Drive it around the block then back to your house. It will take 3-5 restarts before your truck quits running rough. Reason for this is because your computer is trying to "relearn" the firing order. I have done this several times so i know what i am talking about. You can even look it up. Your 2000 expedition is a dang good truck with a great engine. After your computer relearns the firing order then the rough idle will be gone. Then I would take it out on the freeway and run it hard for 5-10 miles. If you experience a miss or two then that means you need a new cop(s). Get a code reader and it will tell you which cop is bad. Cops are expensive. I bought 6 new ones on ebay for $40. If you buy from autozone or ford dealer then you are looking at about 80-100 bucks a piece. Tell me if this helps. Ford makes a good truck and the expedition is a great truck. Mine is a 2000 expedition also. I have 248,000 miles on it and running strong with no burning oil. Good luck.

"Tap" the metal area while someone else keeps the car running. If it starts to idle ok, replace the IAC.

You are really onto it! Either the TPS or the cable from the peddle. Do check the cable first. Frankster016

It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

Don't waste your time. Have the intake manifold gaskets (upper and lower) replaced. Check all vacuum lines for leaks. Clamp all vacuum hose connections.
Do NOT replace any sensors unless the computer codes indicate.
THIS WILL FIX YOUR PROBLEM!

Rough idle & stalling at a stop


This maybe due to a dirty Idle Air control valve or a throttle position sensor. YouTube can provide good answers for removal and testing of the Throttle Positon Sensor (TPS) as well as cleaning the Idle Air Control Valve (IAC)

Do the service below.

Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If this doesn't improve the problem you have mechanical problems in the engine like a low cylinder die to worn rings or leaking valve seats.

I have a 1991 Buick Park Avenue. Runs rough in


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Wont idle right.Idles at 2000 rpm then drops to 900 or less then usually will stall.If i unplug the mass air sensor while it is running nothing changes. Does this mean it is bad? Thanks,John


MAF concerns the proper mixture of fuel, not the idle speed, so it is most likely all right (if it wasn't, your car would die before it reached 2000 RPM's). Idle speed is controlled by a small motor, generally mounted around the throttle plate. This is controlled by a computer, which judges idle requirements by the input from crank or camshaft position sensors. Make sure that all of your sensors are clean, and in proper operation.

Check the air idle control valve, it may not be working or dirty with carbon build up. Check the wire harness to the valve and try cleaning it with throttle body cleaner, do not use carb cleaner. You might get away with just spraying a Can of throttle body cleaner through the throttle body, follow the instruction on the can and use the whole can. After your done, turn the engine off and place the ignition key to the run position for 30 seconds then turn it to the off position for 10 seconds. Start the car and let idle for 1 min before going for a test drive, that will reset the base line for the air idle control valve. Good luck and hope this helps, If the problem still there then the air idle control valve needs to be replaced.

My 1998 Olds 88 has been stalling and running rough.


Check and clean the IAC valve. Idle Control Valve. Use brake cleaner or carburater cleaner . Remove the duct work from the air filter assembly. It is located just inside . Run the engine at 1200 rpms and spray the valve. The valve can also be removed and cleaned.
