Rough idle sitting at long red light

My 2008 Ford Fusion has 51,000 miles on it. It has a slightly rough idle that you notice sitting at a long red light, or turning on the AC sitting or moving slow through a parking lot. Ford dealer tells me this is normal behavior for the 2.3 4 cylinder engine.

SOURCE: rough idle; engine light appeared

I had that problem with my 2005 FX4 turned out to be a coil on #6 cylinder I replaced the coil my self and the light went out coil was $58.00.These trucks are sensitive to water in the gas you may want to add gas line antifreeze or isopropyl alcohol to your gas every other tank to displace any water which may be getting in there.

Usually the fuel pressure regulator vac. hose pops off? If not listen for a slight whistling noise (vac leak).

2008 ford fusion all of the sudden start idling rough when I start it at the same time it will not shift into overdrive on highway and cruise control stopped working. Also the wrench light came on.

With the wrench light on ,DTC'S - diagnostic trouble codes are stored in the module's . This indicates there is a problem with the transmission or the electronic throttle control . Have it checked for DTC'S

Why does a 2006 Ford Fusion have a strong vibration when stopped and in Drive?

If there are no check engine lights could be a bad motor mount or two. Would have them checked. Try putting car in neutral and see if vibration disapates a little.

Today while driving the traction control light, the wrench light and the ABS light came on in my 2008 ford fusion, AWD, what will i need to do to fix this and aprox the cost?

easy you have either a faulty sensor on a wheel or the painted magnetic strip in the back of the bearing has been damaged or the cover the paint sits on has corroded away ,disconnect each sensor in turn and check for continuety first and if all ok then disconnect each one in turn with vehicle jacked up and spin wheel and using meter on lowest miliamp setting to see if you read a slight voltage on a fast spin of the wheel .

Just bought a 2008 Ford Fusion with 41k miles. It has a rough idle when I'm stopped at a long light. Should I be concerned?

I would start with changing fuel filter and run a good fuel system cleaner through it for starters. Then a good healthy tune up would be a good consideration - plugs, wires, all fluids & filters. That will give you a good "ground zero" starting point w/your new car.

I have a 2008 528i that has a really rough idle it has 21000 miles and a decarb has been done. the idle problem is the most noticed when the engine is warm and the car is sitting still. the idle dips but...

A decarb has been done????? Are you effin kidding me? who sold you that? That's like putting a 5 year old on arthritis medication.

Good grief, it's a new car and someone sold you a decarb.......that was their best effort at diagnosis.

Go to another BMW shop......let's see a 2008 w/28kmi. can u say: .WARRANTY!

2009 ford fusion engine light stays on steady

You just have to disconnect the battery for 1/2 hour. then reconnect and drive for 10 miles so computer can relearn your engine again. It may run rough. You should have the key off when refueling because computer sensed a fuel vapor leak during fueling and turned the light on.

Also, you can always drive with a check engine light on. It just means you are not meeting emissions. Do not drive if it's flashing on and off.

I have the same problem with my 2008 4.6 F150 and I think Ford is ignoring the problem with these vehicles.
