If it's yellow that is the check engine light, a fault has occurred in the emission control system, have a trouble code test run by Kragen auto our another parts store like them, it is free post the code back here.

SOURCE: the oil pressure light goes on and off intermittently.

I had a similar problem with my 2003 Sante Fe (intermittant problem, the light went off when I accelerated). I took it to the dealership. They looked for a bad send oil switch (not the problem) as well as some other possible culprits but could not, at first, find what was causing the light to come on (but they did confirm that I had low oil pressure). So, they took the engine apart. What it was was the pan was "dented" upwards, so that less oil was able to come in. It wasn't the bearings. It wasn't the crank case. It wasn't the oil pump. So, they fixed the dent, put everthing back together and . . .it worked! The light went off and stayed off. It cost $337 in labor. I was very very very relieved.

(Apologies if this explanation is hard to follow-I'm no mechanic and am basing my response on my understanding of the mechanic's explanation).

SOURCE: Help! 2003 Hyundai Accent problems. Transmission??

well the first thing you need to do is to pull the stored codes in the computer and see what they say and then go from there, this could be a speed sensor or a trany going bad , i dont know if this is an automatic or standard trany, start with the codes from the check engine light, autozone car parts store will scan the computer at no charge,

Car looses power, bogs down check engine flashes rapidly. No acceleration, then 15 - 30 seconds later power comes back and check engine light goes solid and stays on for 2 or 3 days.Anyone with idea?

You should read check engine code.
It tells you more than you can guess.
You can buy quality $1000 snap-on OBD scanner or $30 cheap one.
$30 will do good job. (you need to google after car tells you error code because cheap scanner shows only code but not meanings in plain English)

or you can visit local autozone and ask them read code for free.
unless you ask car itself, nobody will be accurate.

Daewoo Lanos check engine light stays on but no codes coming up. Is there a way to reset?

I suggest scanned the computer in order to know fault codes stored there, soud like a EVAp or Emissions failing.

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.

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

My check engine light also comes on with my 2005 saturn vue 4cyl. about the same time my engine fan comes on high speed and stays on for days then goes off and the engine light goes off. I changed the...

Engine fan work on high speed in 2 cases , when engine is overheated or when AC is running. If your engine temperature is ok than U have to check the AC system . in most cases the relay that command the fan is the problem.I do not now exactly what kind of fan is on your car but are models that have electronic variable speed fans and the electronic module is located inside the fan.Other models has a separate module that contains the relay and its easy to find the module box only pursuing the cables that leave from the fan
