Hi, when a check engine light comes on it usually indicates an emissions fault has occured. Most of the time you will have no change in engine performance at all. What you can do is drop by your local Auto-Zone parts store and for no charge they will install there obd-2 meter to your computer and it will give you a read out number telling you what the problem is. I carry one in my truck as my light comes on about every 3 to 4 months. They can give you the number for the code and erase the light for you also. You will need to have it checked if you live in Ca before you smog it as if it is on it will not pass.You can do this or take it to a shop to have them check it and make what ever repair may be needed. Auto-zone will erase it and it may never come on again. I have seen this happen also. Keep me posted,

The car runs on a 32 bit computing system.
The computer has senced some malfunction in the engine.... this could be as simple as airfilter choked or as bad as fuel ijectors getting clogged or even worst.
Before any damage starts to happen the computer warns the driver by flashing the Check Engine Light.

It is highly advisiable to get this checked through elerotonic diagonistic systems available with most good garages...

The fuel filter light,battery light and 4 WD light wont go out until the engine reaches 2000RPM

Guessing that the charging-system/battery is borderline. With a voltmeter, measure the battery voltage with the engine off--should be 12.6 volts DC. Start the engine, then measure the battery voltage again, it should be ~13.5 to 14.5 volts. If the battery has a shorted cell, it will decrease by 2.1 volts/bad cell and will probably decrease the running voltage as well. The battery must be replaced if it has a shorted cell. If it has removable caps, check the water level in each (add distilled water only, but don't over-fill). Clean the battery connections with a special wire brush and put anti-corrosion grease on the terminals and posts. Wash your hands after this procedure to prevent mysterious holes appearing in your clothes. Once the battery and charging system check ok, look for the check engine light on. If so, read the code(s) with a rented scanner and pursue to repairs. If no codes, erase the light. Hope this helps!

The check light is continously shown ON

Remove the terminal head from the battery if only you run a scan and there seem not to be any issue or code reported.

But I strongly recommend the scan.

I would have the car checked on the computor.Even if the engine light is off it will store the codes.When you get the codes it should point you in the right direction.I would say it's posibly the throttle position sensor.
