My engine light (ECM) keeps on coming on for a few days then goes off for about 2 weeks. What could be the cause

When the Check engine light comes on it is indicating a fault in the systems of the engine has been detected or a problem in the emission control system. When that light is on a fault code is set, you need to have the fault code read, then based on the code you do the diagnostics outlined in the factory service manual. Any Autozone or O'reilly auto parts will read the codes for free except in the state of Calif.

Kia Optima 2002. Diagram of engine has come up on the dashboard display saying check engine, its flickering on and off and the engine sounds like its missing. It has plenty of engine oil?

The "service engine" light will illuminate for many reasons. Was the engine running good before the light was noticed? It could just need a tune-up (Wires/Plugs/Rotor & points). But you could have had a sensor go bad (Oxygen, EGR, etc) The best way to handle it is to read the computer error code.

Many auto parts stores (ie AutoZone, Napa, Advanced Auto, etc) will read the codes for you (for free) and advise you what you should do.

Take it to autozone or another place like it and have them read the codes and tell us what they are.

I own a 2000 Alero and for the past 2 weeks it has been stalling at the stop lights but runs fine on the highway. The service engine light has come on. Is it safe to run for antoher day until I get it

When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Have a orange engin symbol what does it mean any help please

This is the Check Engine light. Read what causes it below.

When the Check Engine light is turned on the computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible faults that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

Service engine light on mechanics machine read code po456 emmission leak new gas lid was put on two weeks ago light went off for back on in febuary I had the same thing the shop found a pin hole...

It can simply be the gas cap is not screwed down after the last fillup. Remember too that you need to clear the computer code or it will take 25 to 50 startups to cycle the code out of the system. Autozone or Oreillys scans for free and can wipe the memory of the computer for you. Check for a clamp on the fuel fill which joins the filler to the large tank hose. Its under the wheel well.

Since you wrote about the Febuary service, March, April, and some of May could be within 90 days. Also Emission parts are usually covered by Law for a longer time period. You should check by calling Ford, Lincoln, Mercury Customer service and asking about the earlier replacement part(which parts are covered, if its one of them). You may be able to recover some of that $450, especially if a Dealer charged you for a covered repair.

What the repair facility needs is a "smoker" machine which reveals leaks. There is also a solenoid which opens the vapor canister to draw out fumes. The repair shop should test the part they installed to see if it was defective. There have been several reports to Fixya about Mice eating wiring and chewing hoses. This applies to all models of vehicles.
