Hello, my name is Ben. Sorry but there really is no quick and easy way to determine the reason for the light to be on other than maybe check all fluids. About all you can do is have the Diagnostic Trouble Codes (DTC's) scanned with a scanner. Some AutoZone stores will do a scan for you, unless you are in California, where they no longer do it. And the problem with AutoZone is they often will not know how to properly interpret the results of a scan. Still it's a good place to start. Then post any codes you get and go from there. I hope this is helpful to you, Ben.

Intermittent miss at idle and steady speeds

You need to hook up a computer scanner to the engine to find out what the fault code is [indication of what is causing the miss]. The CHECK ENGINE lamp lights up when a fault code is detected and set in the computer's memory. ALWAYS replace all the spark plugs on a Ford when there is a miss. Those "alleged" 100,000 mile spark plugs are really only good for about 60,000 to 65,000 miles. Using them longer than 60,000 miles causes the ignition coils to overheat [from trying to fire the huge gaps on those worn out spark plugs] & fail. Hopefully, you will get a fault code to tell you which cylinder is the problem. When you disconnect the battery, you give the PCM [engine computer] a case of amnesia, and it forgets the fault codes it has stored in it's memory. That's a foolish move, as it only removes the info a "real" mechanic needs to solve the problem. Use only Motorcraft, NGK or Denso spark plugs. Other brands won't last in a Ford product.

1994 Lincoln Towncar is idling and running rough. Have changed the plugs and wires recently and no change. Compression is good..93,000 miles on it. New Air idle pump also. Do you have any suggestions? ...

Is the check engine light on ?
Fuel pressure ok ?
If it has a steady miss on one or more cylinders you'll need to figure out which cylinders and what is missing = spark-fuel-compresson.

Check Engine Light came on while driving. No


Thanks for using FixYa. The check engine light is on because ECM (Control Module) detected a fault with your car's system. ECM has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. You'll need to get the codes checked from a nearby dealer/mechanic. Please revert with the codes so that I can tell you where exactly the issue is.

Please do rate the solution and revert for further assistance.

Service engine soon light is on with a steady light

Your going to have to read the codes. Autozone has the haynes book 15 bucks. It will tell you to jump some terminals with a wire and then turn on the key and read the blinks. I would suggest to just open the hood and take real close look to see if any wires or plugs appear to be disconnected, you may get lucky. In either case once you have the codes youll know exactly whats going on. Good Luck

99 taurus running rough smells funny light flashing

The reason the check engine light is flashing instead of on steady is because it is missing bad and the car companies did this to tell you to stop the car as soon as possible to prevent damage. That is the only time the light will flash off and on instead of being on steady.
The cause is a little harder to diagnose. It could be a fouled spark plug, a bad plug wire, an injector, stopped up fuel filter. I can't remember if that car has the distributer or the coil packs but you could have a problem there. If you have never changed the spark plugs or fuel filter, it is well over a hundred thousand miles to do so now. They say to change them at one hundred thousand but 50 to 75 thousand is better and you will get better mileage. The fuel filter needs to be changed every 20 thousand miles now days because of all the cheap gas we have to put in the cars.
This is for mechanics or technicians. If no one out there believes me about the mileage on the fuel filter, then take the filter off and see what comes out the back. Looks like black water to me.
