Where is the pcv valve 2006 ford five hundred

It is under the throttle body area and it is hard to get to unless you are doing the plugs and have it out of the way. My Ford dealer quoted $166 to change the plugs P&L. I did them myself. Look up your PVC valve on to see what it looks like.
1. Remove the 4 transaxle roll restrictor brace bolts.
o To install, clean the bolts using a wire brush, apply new threadlocker to the threads and tighten to 55 Nm (41 lb-ft) .
2. Remove the bolt and the transaxle roll restrictor brace.
o To install, clean the bolts using a wire brush, apply new threadlocker to the threads and tighten to 48 Nm (35 lb-ft) .
3. Disconnect the positive crankcase ventilation (PCV) valve tube from the PCV valve.
4. If equipped, disconnect the PCV valve electrical connector.
5. CAUTION: A new PCV valve must be installed if removed from the cam cover. Damage will occur to the locking mechanism on the PCV valve. Rotate the PCV valve counterclockwise to remove from the valve cover.
6. To install, reverse the removal procedure

The car will idle low on and off and the idle is a little rough. I have a new pcv valve, new air filter, new spark plugs and wires, new timing belt.

The first thing I would look at is the EGR as they could make your car run rough Located just under the throttle body

Engine won't start when it's warm. Acts flooded. Can usually get it started after 5 minutes or so. Runs rough for 5-10 seconds and then works great. 27-28 mpg. So far changed plugs, one plug...

try running a good injector cleaner thru it- sounds as if you have a(or a couple)weeping injector,
try LUCAS injector cleaner- works on my sonoma

MPG has dropped

Air filter? And any car I have ever owned with a timing belt has shown a noticeable drop-off in MPG when the belt had some miles on it. I would do what you have done but added (or at least eyeballed) the air filter. If that didn't bring it back, the timing belt was next since it doesn't take hardly any stretching to throw off the valve timing and it is critical to performance and MPG.

My mpg's are way down I am only getting about 105 miles per full tank of gas. I put new spark plugs in and a new 02 and still mpg's are way down what do I do next?

Try a major tune up (spark plugs are only one part of it) fuel/air filter, PCV valve, cap, rotor, spark plug wires and adjust timing..

here are a couple of different problems that will cause bad fuel mileage. first is air filter, still getting low mpg. then the pcv valve. clean fuel system. the cost of filter about $20 pcv was $12 and the fuel system cleaning and pcv is easy to do. when cleaning the fuel system,clean the injectors the fuel rail and the throttle body be sure that you have them change the oil or that you do it after they work on it. Notice whether the oil smelled like fuel then your engine needs platinum plugs for best spark they can run as much as $8 each.

Low mpg

YOu could try the computer reset. it may help. Other things you can try are running a higher octane gasoline, or the next time you fill up get a container of fuel injector cleaner, or fuel system cleaner. This will help to get rid any deposits that are built up in the engine

Chev. S10 starts but stop's immediate when hot

check compression, at that many miles the exhaust seats could be wearing up into head causing valves to stay open longer loosing compression,while the engine is cold oil is thicker ,lifters pump up further do to thick oil when oil thins out you have less lifter pump up thus working working properly check compression cold should be 125 low to 155 any less than 100 you have valve prob.
