More than likely it is one of two or three things.
1. The O2 sensor - i.e. oxygen sensor
2. The EGR valve - i.e. inert gas recirculation valve
3. or something in your emissions system
The best way to find the actual problem is NOT to just start "swapping parts" rather have a mechanic read the code or codes that the on-board computer has recorded. Or, you can buy a code reader at an auto parts store and do-it-yourself, just follow the manual.
Hope this helps.

I believe you can get a "code" by turning the ignition key on and off three times then back on and wait for the check engine light to blink.
You gotta watch careful
It might only blink once pause then two then five.
What you have to do is count the flashes and write them down. That code will tell you what the problem is.
Assuming none of the other lights are red or amber it is safe to drive but watch the temperature guage and the oil light or guage carefully.
You might have and emissions sensor going but the code should pick that up.

probably a problem with your exhaust system sensor known as the O2 sensor. Many dodge products will turn on the check eng light at a certain mileage then you replace it and have the code reset. Or your car is just running poorly but not poorly enough to notice so the light comes on the tell you to get your engine checked. So go get your engine checked and your codes read at a parts store or garage.

My experience has been that the check engine light is usually coming on due to an emissions issue. I would take it back to Auto Zone and have them check the codes again, and ask them what code they are getting. Then research that code at your local library to find out what it means-most libraries have a suprising amount of make/model specific manuals. It could be something as simple as a clogged air line.

OK DAVE LET ME SCHOOL YOU , first let me say that you did a stupid thing , by replacing parts BEFORE YOU EVEN CHECKED THE COMPUTER FOR CODES !!!!!!!!!!
you also have a 1994 plymouth , this is a obd1 system , the person who said turn the key on and off 3 times is correct , on and off 3 times and stop at the on position on the 3rd time , count the flashes of the check engine light , will be long flash ( tens ) short flashes (ones ) i .e. 2 long flashes followed by 3 short flashes is code 23 , and so forth , and STOP TAKING ADVICE FROM PARTS PEOPLE AT AUTOZONE , THERE IS NO CODE FOR FUEL FILTER , PLUS ASK ANY OF THOSE GUYS AT AUTOZONE WHAT KIND OF AUTOMOVTIVE DIAGNOSTIC TRAINING THEY HAVE ....... HERE ILL ANSWER THAT
( NONE )...... DAMN YOU PEOPLE PISS ME OFF , YOU HAVE A WARNING LIGHT ON , AND THEN YOU ASK WHAT CAN THE PROBLEM BE , AFTER YOUVE SPENT NEEDLESS MONEY , AND GO TO PARTS PEOPLE FOR AUTO REPAIR ADVICE ....
KEEP SPENDING MORE MONEY , AND WHEN YOU HAVE THE CODE # OR INFO , THEN RIGHT IT DOWN HERE SO PEOPLE CAN HELP YOU , OR DO YOU EXPECT US TO TELEPATHICLY COMMUNICATE WITH YOUR P.O.S.

Get in the car and insert the key. Turn it to run then off then run then off then run then off then run. Count the flashes of the Check engine light. For example, 2 flashes with a pause and then 4 flashes is a code 24. Count all the codes till you get a 55. Call the dealership and ask them what each code means. BTW 55 means end of codes.

i own a repair shop,and usually the cause for this and it wont always show up is a bad 0-2 sensor,these will cause problems but not throw a trouble code in to the computer and this stumps a lot of mechanics,i have had them in the shop that did not show any trouble codes at all,and the 0-2 sensor would be bad,you can replace it and usually it does fix the problem,computers aren't perfect,and they wont always pick up a code from a sensor,id at least take it out and look at it,you might be able to see damage to it by doing this,good luck with it,i hope this help,s.

hey mr dodge man , there you go sending this poor kid on a wild goose run , HE SAID THE CHECK ENGINE LIGHT COMES ON !! plus he never gave any symptoms , so how can it be an 02 sensor , also ive never been able to look at an 02 and see if it is damaged , but hey maybe he can take it to your shop and you can look at it for him . ( the 02 ) . kid get the codes first , then research the code info , this will lead you to a correct diagnostic route .
