Single female with intermitatant emission problems(please help)
For about the last year every three months or so my truck(automatic,3.4L 6 cylinder) will start and idle very rough.When I put it in drive it does not want to move.It will go fine in reverse,low and 2nd.After a few minutes it will start running fine and do so for several months. I have noticed if I put regurlar unleaded in it it will be worse.I have changed the transmission fluid and filter.It has been about 2 years since I changed the fuel filter.Also the gas milage has dropped from about 21 miles to the gal. to 17.The problem seems to happen when it is hot,like when I drive about 20 miles and then stop.Like I said it only does it every tree months or so.Hard to trouble shoot like this.
The check engine light does not come on.I have run diagnostics anyway in case the light was bad and it does not pick up any codes.
I have been trying to check the EGR valve and every diagram I find seems to put in a different location.

Re: Single female with intermitatant emission...
I vented yesterday about GM so won't repeat it here.
You should be able to locate the EGR valve by checking anything attached to the exhaust manifold and following lines.
The EGR is typically equipped with a drum shaped housing with fittings on the top and bottom, sometimes (often) mounted on the exhaust manifold itself.
The drum houses the diaphragm that is controlled by vacuum and opens a small path between the exhaust manifold and the intake side to inject (supposedly) some unburned gases to burn again.
Since we are kind of anonymous here, I can admit to having cheated all of them since it mostly brings a little more mileage.
Stuffing a ball bearing in the vacuum hose and reattaching it to the EGR lets it appear to be functional.
While still in CA, we never had a vehicle fail emissions testing despite this 'cheat.'
If the EGR valve has failed and stuck open, then exhaust gases are entering even at an idle which can cause the symptoms you describe.
Engines running at mid-RPMs can tolerate the garbage being fed them without gagging, but not at an idle.

What happened to the shop that did the work,why can't they resolve
Those issues are from either not changing your oil enough or failed VVT Cam Actuators,sometimes the chain guides wear but not on a 2006,too new
Exhaust Converters fail from leaking injector, which is a know problem on your motor from 2004,05 & 06, & bad COP Ignition Coils, which causes cylinder misfires & ruins the converters
All of the issues could have been prevented & all of the coil are bad by 6 to 7 years & both upstream oxygen sensors need to be replaced at 100,000 miles
Too bad your not my neighbor,you won't have one problem The transmission will fail next, from not changing the fluid every 3 years
I happen to know the vehicle & ford/lincoln issues
Exhaust Converters last 14 years & still pass emissions inspection if your proactive & road test & take a scanner with you a 2 or three times a year & look at all data parameters & keep an eye on things
Just to drive any vehicle with todays technology & never look at data or do preventative maintenance or know what is needed & stay up to date using the internet every month,your going to have problems & serious ones at times
It is a single wire coming out of the harness that goes across the cylinders 2,4 and 6, about center of the vehicle.
You probably need to use a mirror to be able to see it since is hanging down behind the engine.
I hope this helps.
Are these factory OEM replacements? I once put three cheap aftermarket Kragen batteries in my Corvette in 6 months, bought a Delco and problem solved, that was years ago. Sounds like your problem is that the car sits to much, if it sits more a few weeks either hook up a float battery charger or disconnect the negative cable to the batt.
no it is not dangerous, but it is illegal. the catalytic converter is an emission control device designed to regulate pollutants produced by the engine. if your coverter is plugged it can potentially cause damage to your engine because it does not allow exhaust to flow properly. this wont happen over weeks or months, but long term, such as years can cause damage.
