Question about 2006 Ford Fusion
My car is sluggish, and emissions light is on. I changed my rear 3 ignition coils and issue seems to be something else. My emission light flashed yesterday. what could I check? could the catalytic converter cause this?
Check for vac leaks or what is the code for the c/e light? also did you replace the boots on the coils or use the old ones have you tried new spark plugs it would really help to know what codes are

No the cat converter can not unless it is plugged but the cylinder misfire can cause the cat to go bad. a engine idling high means a vacuum leak and misfire.

Your escape is a 3.0L duratec motor. Is the motor itself overheating or just the pipes? The high idle is often related to a dirty Idle Air Control module or IAC, which is located on the top of the motor near the throttle body. If you clean this, or replace it, after a few days the high idle is often times solved.

have the vehicle scanned for error codes at autozone, its free. Post codes for more help....These engines have issues with the COPs (ignition coils-over-plugs) failing prior to 80k miles. When they fail typical problems are: Sputtering under load/acceleration, rough idle, random misfires, random stalling, light or heavy jerking under load (usually at 15-35mph and 45-65mph)..hopefully this helps!!

SOURCE: failed emissions test
First, thank you for asking me for my input on this. It just so happens, that I used to own a Ford ranger that had the same engine as yours. It was a 1990, but there are few changes to these model years.
Anyway, there is only one reason that your HC levels would be high. Your engine has WAY too much unburned fuel in the exhaust. The same reason applies to high CO levels. Too much fuel and/or not enough air.
Below is a link that you may find very helpful. It explains exactly what we are talking about here and also lists some of the possible causes.
Incidently, when I had the same emissions failure on my truck, replacing the air filter and replacing a failed MAP sensor fixed it. - I did NOT have to replace the catalytic converter. If the numbers are as high as you listed above, you will only destroy a new converter anyway because there is obviously not enough oxygen in your exhaust system for the catalyst to function properly. Those numbers are nearly DOUBLE the allowable maximum. If the engine is running correctly and the catalyst is good, your numbers will be WAY BELOW those maximum numbers.
Please understand that I am NOT telling you to replace your MAP sensor without proper diagnosis. There are many possible causes here. Please click the link above and read the article. It will help you to understand what is going on here.
