SOURCE: service engine soon light come on

There are TONS of reasons - the first , and least expensive, step is to read the codes that the onboard computer is throwing. Instead of spending a lot of money on a code reader, or wasting money by going to the dealership, find an AUTOZONE (or, sometimes MERCHANT's will offer a "we'll check your CHECK ENGINE LIGHT for free) and they'll give you a generic read of the code(s).
I say "generic" because the computer DOES throw specific codes; the "we'll do it free" places usually don't have the same kinds of super-readers that the dealerships or high-end repair shops own. But, bear with me for a sec....this may save you some money.
If the generic code says, "O2 sensor"....that's not as specific as you'd like (because there are multiple 02 sensors!)...BUT....if ONE sensor is not functioning properly, its a pretty good bet that the other(s) will be failing soon too, since they were all installed at the same time and all were made by the same company, etc.
The "generic" code WILL tell you enough info as to which sensor is bad (the one in front of the converter vs the one behind the converter) so....if THAT is the code, then simply replace both behind or both "in front". Follow?
Now, where you'll typically get the most common code is for low fuel pressure. If you've never changed your fuel filter...that's a good place to start. The "generic" code will indicate "fuel pressure". If you've never changed the filter....see? BUT, a fuel pressure problem could also be as simple as "loose gas cap"! If your generic code says "fuel pressure", then I'd reset the computer (disconnect the battery for a few minutes and re-connect), and while the battery is disconnected, make sure that the gas cap is tight and the little rubber gasket around the cap is in tact.
Keep in mind....a "check engine light" doesn't mean that your computer is throwing codes CONSTANTLY! It means that the computer sensed something at some point while the scan was running and SOMETHING got its attention. "IF" the fuel cap was loose, for example, just re-tightening it will not reset the "check engine light"! You gotta reset the computer (disconnecting the battery is easiest), THEN the light will be off. If the light returns, then the problem was something other than the gas cap.
Taking your time and doing a little on-line research can save you a ton of money! A 2000 is relatively easy to work on yourself...at least SOME of the issues...even if you're not a really techie-kinda person. Take the easy and inexpensive shots first....
Hope this helps.

SOURCE: service engine soon light,

I would take it to a major auto parts store and they have diagnostic machines to check your system for errors and let you know what they are. they will also clear them to and the light will go off. But this is the most accurate way of knowing without spending a lot of money

SOURCE: 2004 chevrolet tracker,how do we fix the service

Thats just like a check engine light. Take it to autozone and ask them to check for trouble codes. They do it for free. that will give you some idea what is going on, but if they try to sell you anything, don't buy anything until you get a second trustworthy opinion.

You need to get the fault codes read to determine where the problem is that set the SES light. Autozone will scan your car at no charge. At some point you will need to get a mechanic involved to further diagnose the codes.

I have a 2004 3.9L Mustang with the "check engine soon" light on. I read the codes and 0300, 0301, 0305 and 0316 were up, while the car was still driving fine. Soon, it started to lose strenght, I bar


Best to read the codes first---code p0300 refers to random multiple cyl-- misfire detected causes-- spark plugs---HT leads--ignition coils--wiring.
code p0301 refers tocylinder 1-- misfire detected causes ---engine mechanical fault---wiring---ignition /fuel system ---injector---ECT/Maf sensor(Mass air flow) ECM.
code p0305 refers to cylinder 5 misfire detected causes ---same as 0301
code p0316 refers to misfire detected during start up -first 1000 rpms---causes--- engine mechanical fault---wiring----ignition/fuel system---injector. I would run a fuel system pressure pressure test as the common causes here is the fuel/injectors

My 2004 mustang gt service engine soon light started flashing for about a minute and went off also my car started


If your check engine light starts to flash that is telling you to shut it down so that you do not do any significant damage to the engine. I would recommend that you go to your local parts store or call a mobile tech out to read what codes are possibly stored in your cars computer and find out what is going on.

Running rough/service engine soon light


SOUNDS TO ME LIKE THE PCV VALVE MAY BE STUCK OPEN OR THE VACUUM LINE ON THE THROTTLE MAY BE SUCKING OIL INTO IT. PULL OFF THE AIR INDUCTION HOSE AND LOOK INSIDE THE THROTTLE BODY TO SEE IF THERE IS THE PRESENCE OF OIL.OPEN THE PLATE AND SPRAY GOOD CARB AND CHOKE SPRAY INSIDE WITH AN OLD TOOTHBRUSH TO CLEAN IT OUT. SOAK IT UP WITH A CLOTH RAG. WAIT A FEW MINUTES TO START CAUSE IT WILL HAVE TOO MUCH FUEL IN IT TO START. HOPE THIS HELPS. LET ME KNOW PLEASE. BEST OF LUCK.

The cheap and easy way is to disconnect your battery and turn on your headlights and leave it for a few minutes to reset the ECU. Otherwise you will need a scan tool to do it.
