Question about 2002 Lincoln LS

1 Answer

My Engine check warning light is on in my 2002 LS, and after 3 cold engine starts running high octane fuel, it has not reset itself. my car runs great while in drive but has a rough idle when stopped. This occurred after my fuel tank ran really low and I only put a few gallons of fuel in to get me home. The rough idle and light happened the next morning from a cold start. I filled it with premium gasoline but see no improvement.

    DO NOT run any fuel other than the recommended Octane, if you do you cause cold start problems. As far as the check engine light you MUST have the system tested for the fault codes that are stored in the computer when the check engine light is turned.

Hello, Take your car to an Autozone, Oreillys, or Advance autoparts store. Any of them will give you a free scan for the cause of the "check light". You may be able to buy the correct part to fix your car and it may be a simple matter of switching a part on a connector.

The Parts guys will be able to tell you where most of the parts go and what is needed to change them. After the new part is installed you may need to have the onboard computer cleared or you will see the old warning for some time.

If the scan shows nothing, then a fuel sample with a change of the fuel filter would be the next step I would take.

If you have any trouble Code numbers to identify, you can send them here and we will identify them for you.

Is Premium and higher octane better than regular gas in Mazda 3, 2012 car?

Octane ratings have nothing to do with fuel economy or power. The octane rating only indicates how much the fuel air mixture can be compressed before it ignites without the spark plug firing in a hot running engine. Some really high compression engines require higher octane fuels so they don't knock when running. If you don't have a sticker under the filler lid that says you have to use one of higher octane fuels, then don't use high-test.
It used to be that using a low octane fuel in an engine designed to use high octane fuels could damage the engine.
Nowadays, engines are all computer controlled and most high octane engines will re-tune themselves on the fly so that they don't knock if the wrong grade of fuel is used.

It takes about 8-10 times of trying to start up my 2000 mitsubishi galant in the morning(the first start of the day) but during the day when the car is in use and the engine is warm it starts up easily...

Three things might do this. You did'nt say what year model or engine size to the answer is'nt your car specific. The car does run with the check engine light out? If it's running with the light on, you can stop at an auto parts store and they can check to see why the light is on. The coolant temperture senser can make the engine contol computer (think) that the engine is warmer than is is and not shoot enough fuel to keep the engine running good as it's cold . The engine takes less fuel to run hot and theirfore it runs OK. the fuel filter or the fuel pump could not be letting enough fuel pressure to get to the motor and again as the engine warmes up it needs less fuel and runs OK. Sometimes peaple put high octane fuel in an engine that does'nt need it and the high octane fuel burns slower and when the engine is cold it doesn't make as much opresure so it's harder to keep running but as it warme the presures of combustion are higher and the engine runs just fine. If the oil weren't change don the regular time and the oil is old the engine compression might be a lot less than it would be with good oil and the engine may have to warm to have good compression tp run well. If this is the case the oil may need to be changed a few times to get it clean enough to run well.

What grade of fuel do i use in the v8

Your car requires a minimum of 91 octane gasoline. If you use a lower grade fuel, it can cause a condition called detonation (sometimes called engine knock) this will cause serious engine damage.

I have a 2002 saturn L 200 series it will crank and and run as long as it is in park but as soon as i put in drive it shuts off?

you may have an idle control sensor bad,is check engine light on?it's most definetly a fuel issue.if check engine light on, have it code read. sorry, you have to take it to a dealer or a reputeable place you trust. maybe someone who has worked on your car before. not just anyone. you need someone who has a code reader above 1999 it very cold where you are? you may need to let it warm up more than just a few may be only cheap fuel.87 octane fuels cheap,but misleading,it may have ethenol in the fuel. try 93 octane fuel for a 1/2 tank or add octane booster to the tank.don'nt know where you're at in world, but cold weather has effect on any engine in any vehicle.if check engine light is on, suggest you have it code read, it can cost a fortune replacing sensors,without knowing which one is bad.but your problem seems fuel related,suggest you add lucas fuel treatment to 1/2 tank of gas 93 octane fuel please.follow instructions on bottle,can get at auto zone,advance auto,nappa auto,just to name a few.but in the end if all else fails,suggest you replace idle control sensor.

Vibration at idle

it may be idle control sensor or a bad mas air flow sensor--maf sensor in otherwords. or could be engine misfire at cold temp. start. only time when cold? or does run better when warm? try warming engine to operating temperature before driving,if problem removes it's self after warm up,up grade gas to 93 octane for 1 tank full. then see if problem goes away. it's cold where you are right? if so the fuel needs to be at least midgrade 89 octane fuel because 87 octane fuel will not start your honda correctly at cold temps. in cold weather 93 or super gas octane will start ,no problem,low octane fuel sometimes gels, or freezes at low temps. if in warm climate, change the fuel filter, add fuel injector cleaner to your fuel tank[preferablly lucas fuel treatment] this will lube your fuel injectors and give better fuel mileage. thank you for choosing

I get a warning message, "HIGH ENGINE TEMPERATURE-STOP ENGINE" from our 2002 S60 Volvo upon starting. The check engine light also comes on. The electric fan come on and runs for approx. 2-3 minutes....

Mine is doing the same thing. I have taken it to the shop and the mechanic can't find anything wrong with it. When he resets the diagnostic, the car runs fine for a few days then it happens again. I'm thinking it is something due to the cold temps here in NW Iowa. It is obviously not a cold weather car!

Engine Check Warning

The problem you are going to have is that you won't know when something else goes wrong. You need to have it reset, but there are ways you can reset it your self. The best way is to go online and find one of the hand held devices that can do it for you. Also you can get a remod computer to lower the need for such high octane also. There are several user friendly computers that you can have installed on your dash or in your dash that allows you to controll many things on your car. Dealerships don't tell you this because how could they get there $100 for doing nothing. Check out painless and the speed channel network online. You can find all the computers to change the octane needed. Also you can get a cheap hand held device that will do all the stuff the dealership does for a one time hit rather than everytime something comes up.

hope this helps

2002 Regal - Engine kills right after starting cold.

There are 3 things that cause this, 1st and most common is a dirty idle speed control valve, 2nd is carbon on the back of the intake valves, last but not least is the wrong octane of fuel, if it requires 89 Octane and 91 or 92 is used the engine will stall code.

To clean the dirty idle control valve follow this procedure:
Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
