- If temp guage reads normal, the lack of heat may be due to the Heater Control Valve. Located in front of the radiator. Lower passenger side. A real bugger to replace.
- The plastic cap just over the thermostat is key in re-filling the anti freeze and bleeding air.

my etc light came on and i took to the lincoln dealer it was my fuel system and it had to be replaced for the tune of 800 dollars. after that it ran fine for about a month then i hit a hump then it went into etc mode again. i then took it back to lincoln they did not see a code or that it even went into etc mode because i cut the car off and turned it back on it ran fine but once you cut it off it resets itself it did this about 10 more times and never came back on again knock on woods no problems but it started missing and the check engine light came on it was a misfire in cylinder 4 and it replaced the spark plug myself and it has ran find ever since. I was told anytime the etc light comes on it due to fuel or transmission

It could be the dccv or the evap. discharge sensor,driver's temp sensor or pass temp sensor. Without hooking up a tester to read pids there is no way to tell. I would recommend going to someone that has the ids tester to read pids. good luck.

If you have a 2004 lincoln ls,the PO420 is-- Catalyst System Efficiency Below Threshold. ( Bank 1) The list of possible causes are long. I have the same vehicle, and the Emissions Manual,which is several hundred dollars. Don't let anyone tell you it is a bad Converter. It may be, but it is only six years old. I would check for codes. The ignition coils (Coil-On-Plug) go bad on all Fords and a misfire, resulting overheating of exhaust system etc,will set all kinds of codes,and they may not be related, to the real issues. Lincoln is where one of everything goes,when it comes to the latest technology. Check that the O2 Sensors are screwed in tight. Later on you may need to have them checked out,if no ignition issues or malfunctioning coolant temp sensor issues. Use only 5-20 Oil. I use Mobil 1 synthetic. Hopefully your not using any,and ruining the converter. Make sure you have the system full of coolant,including the Degas container,the one where antifreeze mix goes. Remember GO5 Yellow antifreeze on ford products. Also bleed the hose next to the brake booster to let out air,in the coolant system. You can check for above normal fuel pressure. I would not go to a Dealer and spend more than necessary. Find a good shop that knows these vehicles. You can't fix every problem on all makes that come thru your doors today. Hope I give you a start on things to have checked. I would stand in the service bay by the car and have the tech prove what is wrong before I would authorize any part replacement.
