Do you observe abnormal idle speed? It may be just an indicator fault; not a really engine firing problem.

SOURCE: 02 navigator misfire #7 cyl still after i changed plugs and coil

You've tried everything but getting the timing checked out. You've done all the other parts of a tune-up but that.

When you changed the spark plugs did you notice #7 was especially dirty or greasy, this could point to a seal being broken or a piston ring that needs replacing.

SOURCE: I have a 2005 Lincoln LS with an intermittent

I have a lincoln ls 2002 and have had the same problems. It is corrected by changing the valve cover gaskets. The oil leaks down into the coils and fouls them out. You will not see the oil around the valve covers on the outside but this should fix the problem. It worked for me

What is the problem of my mitsubishi lancer why the "SERVICE ENGINE SOON" still warning on?


Hi there:
When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.

The Four Most Common Check Engine Light Scenarios and What to Do:
* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Engine light comes on and states "Service Engine


Hello,

The problem is not from the connection from the battery to the starter. There are some problems a car develops due to the fact that it has been used for a long time and have not been serviced.

Like man, when we get ill, we seek a doctor for treatment, so also are cars, when they work for too long, they tend to come up with faults.

Once a car brings up the "Service Engine Soon" message, then you need to know it will either pack up immediately or soon.

So what you have to do is for you to service the engine.

Take care and good luck

When I start my 2001 alero the anti-lock, traction light, service engine soon, service vehicle soon lights all stay on all the time. But my car seems to be running fine. Why is this?


the anti-lock and traction lights will come on together if there is a common problem with the two, since they are closely related. may be a wheel speed sensor or something similar. the service engine soon light indicates a problem with the engine computer, can be anything from an emission system problem or an engine performance problem. all of these lights can come on with no apparent running problems on the car. the service vehicle soon light is basically a maintenance reminder, an oil change light. take the car into a shop and have the codes read for these lights.

I have a 2003 Mitsubishi Galant ES and after checking my oil, my service engine soon light came on, it is time for an oil change, can this be the reason for the light or is it something more?


if your talking about the check engine light being on, no, it will not come on because of oil service time. you may of left something off. if the dipstick or oil cap is loose this could set a code.

Steering hard /loosing pwer at 40-55mph


Take the car in for a new serpentine belt and tensioner right away before you destroy the engine. The alternator, power steering pump and waterpump are not turning right now because the belt has come off. The battery will die soon because it is not charging, and the engine will overheat and perform it's own little rendition of the china syndrome. When the red warning lights in the dash come on, it generally means; park it unless you're being shot at.

Engine check light is on my mitsubishi chariot


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors 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 you need to diagnosed and repaired it. There are test that need to be performed the find out the cause. The light will stay on until the problem is solved.
