SOURCE: car runs rough at idle

clean out ur throttle body, just follow the hose from the air filter to the throttle body. Need 2 people to do this. Don't remove the hose completely from the throttle body. Just enuff to be able to spray ur intake cleaner into the throttle body. Do this especially if its worse when the motor is hot, as this would confirm the problem.

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.

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.

Engen problem and missing


Sir, your question is not very clear, but I will still try to post a solution here. Engine missing could be due to any problem in fuel system, ignition system, engine or ECM as well.

LOW ENGINE IDLE SPEED (Poor idling):
-Throttle body (do the cleaning and idle speed learning)
-A /C signal circuit
-Fuel pump control circuit
-Fuel pump
-Intake system
-P C V valve (clogged or open) and hose

ROUGH IDLING:
-Cylinder Compression
-Ignition system (Igniters, spark plugs, wiring harness)
-Spark plug fouled, gap too wide or too short. (1.00-1.1 mm)
-Fuel injector circuit
-E C M power source circuit
-Fuel pump control circuit
-Fuel pump (required pressure 44 psi - 49 psi)
-Throttle body (cleaning)
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Heated oxygen s ens or
-Mass air flow meter
-Idle hunting
-Throttle body
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Mass air flow meter

HESITATION/ POOR ACCELERATION:
-Fuel pump control circuit
-Fuel pump
-Spark plug
-Ignition system
-Fuel injector circuit
-E C M power source circuit
-Mass air flow meter
-Throttle body (do cleaning)
-Intake system
-Valve timing
-Cylinder Compression

White smoke and foam in the gas tank indicates antifreeze leaking into the engine somewhere. Do you smell antifreeze? You may have an engine seal leaking, most likely head gasket. It may be affecting the various engine sensors.

Sometimes my 95 subaru legacy won't start. It sounds right just doesn't start when it finally starts if you hit the gas it dies no noises just dead.I replaced the fuel pump,o2 censor,not the problem...


I would check air flow sensor(MAF).
Just had Subaru with the same problem , at times it was hard to start , and when it finaly starts no power, rough idle , no acceleration.
I belive your car is OBD I , so you can try to disconnect air mass sensor while it's running , and see if it's any better.

Find your air mass flow sensor in the stiff collar of the air ducting immediately after the air filter. Have the engine running and disconnect the plug to the MAF. If this makes the car run evenly again you need to replace the broken MAF. The misfire on plug 4 I think is a downstream event of the MAF not sending the right info to the ECU and consequently not providing the right fuel / air mix to the engine

I can't give my jeep much gas or it will backfire and die. i have changed the tps and the mass air flow sensor and the fuel pump, 2000 grand cherokee.


Have your fuel pressure checked. It may be a bad regulator.

Try cleaning the throttlebody and air filter.

Check your spark plugs, coil and wires.

Check and make sure all of your injectors are clean.

Also you may want to check your o2 sensors. You can unplug them and drive a bit. If the problem goes away then they need replaced.

Engine starts but will not idle, i give it gas but will not sustain in running afyer 2 seconds engine dies


check all spark plugs and wires also check mass air flow senser located on intake tube if all is still in good working condition check the throttle position sensor if that is good then it may be your fuel pump please update when possable.

1995 Ford Windstar with a rough idling 3.8 L. engine.


the speedo gear is in the tranny in that model i believe so thats a seperate issue..

to the rough idle, it could be a multitude of things. the MAF could cause it, you can get one online for cheap. cleaning it is sometimes not enough.the o2 sensors do one thing, that is tell the ecm how much fuel is being burnt in the cylinders, if it is too rich it leans out, if it is too lean it gets rich..

put the vehicle into drive with your foot on the brake, slowly give it gas if it revs like normal it is a spark/ignition problem, which can also be low compression. if it doesnt stumble and run bad with a load on it it is most likly a fuel issue. you have to rememeber that if the o2 sensor is bad, it will cause a misfire by pumping too much fuel into it. try a compression test, remove all plugs, screw in tester, crank engine, record psi. if the psi is lower than %15 of the highest rating then the cylinder has low compression. add a teaspoon of fresh oil into the cylinder and repeat test. if the compression goes up the rings are faulty. if not it could be a bent valve or somethign along the lines of a valvetrain problem.. good luck
