What could be wrong if your ABS light goes on sometimes and sometimes it doesn't come on at all?
There is something going on in your brakes (ABS that is) most places do brake checks free of charge. Go to Midas if there is one near you, they are the most honest.
My first impression is to check the fuel filter. Other than that, I'd need more information. Does a "check engine" light come on? Have you tried to read the diagnostic codes?
My 94 ls 400 did the same thing. After several expensive parts replaced, I replaced the plugs and wires, and all acceleration/ sputtering/ smoking problems stopped. Hope this helps.

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
This is a transmission related code being stored in the car's onboard computer. I believe this fault is under recall by Toyota. You can find out by contacting your local dealer or looking it up online at the National Highway and Safety Administration. Their live link is on my bio page and on my links page at my home site, AutoServiceTech.com Good luck!
Does the check engine light go away after the problem its fixed?
Yes. Once the car's computer is no longer see the malfunction, it will no longer turn on the check engine light. Have the car diagnosed to find out the exact problem.
Can you drive your car when the check engine light comes on your 1998 Mercury Mystique?
Yes, but if it stays on you should plan to take it in soon to have the engine checked. That is why the light is there.
Other causes include injector, coil, wiring, and internal engine problems.
It is most likely your coolant temp. sensor. If you face the engine from the front of the vehicle it should be just under the head near the back of the engine on the left. When the sensor is unplugged the fan will stay running all the time. Most likely the sensor is malfunctioning at a certain point. A late camaro running at 200-230 is perfectly normal. The fan should kick in at around 230. Good luck
AnswerThere is a sensor that tells your fan when to kich on, sounds like its shorting out. not likely that the sensor is shorting out. The sensor is located in the radiator and aparently the radiator is getting hot. The causes are many. usually heat is acumulated in the radiator two ways. The water pump isn't circulating the water properly or the radiator has some stoped up cores. the fan is normally used while the car is at idle because there is no air flow while siting still. so theoretically the car wouln't need a fan if the car was in a constant forward motion. Also the thermostat could be causing the problem. To find out what it is for certain the thermostat would have to be removed. the reatach the hose. Fill with coolant and coolant lost. open radiator cap. now start the car. watch the water in the radiator through the filler cap. it should be flowing. if it isn't, its the pump...if it is it either the radiator or thermostat. to check thermostat, put in boiling water and see if it opens. they generally open at 180.0 . other things such as a bad radiator cap or leakes in water lines can cause heat acumulation du to lost pressure in the cooling system making it more difficult to cool. not puting antifreeze is a no no in all vehicles which can case things to rust and stop up.
AnswerIf it takes about 2 minutes for the fan to start and SES light to come on, then you have a faulty component. When the car goes into closed loop a sensor or what not isn't working correctly and the fan will sometimes run pretty much constantly and cause the SES light. Have it scanned and repair the malfunctioning part. It should fix the fan. Unless the temp gauge is reading high, over 200*, then it maybe heat related.
The problem is the air injector pump. Most likely the fuse is blown. Fuse is located in the fuse and relay box under the hood next to the air filter housing. Try replacing the fuse and when doing so, listen for the pump to start running. Should sound like a dentist drill. If the fuse blows again or pump does not run, unplug the pump and reinstall the fuse. The pump is supposed to start when you first start you engine. When engine is cold, the pump runs for 3-5 min. If the circuit is broken by a blown fuse, the SES light will come on when the engine goes into closed loop. Hope this helps.
How do you reset a check engine light on a 1995 civic?
You can either try removing a 7.5amp fuse for about 10 seconds in the fuse box under the hood that says back-up on it. Alternatively, turn your car off. Press the oddometer reset button. While holding it, start the car half-way, and lights should start flashing. Keep holding for another 10 seconds or so, or until the lights will go out. Then, turn car off... wait a little while and turn it back on. This should reset the light, but it will come on if you still have a problem eventually. Enjoy.
Why does the check engine light stay on for a Kia 1999 Sportage?

yea do that and if doesnt work there will be some wires underneath your glove compartment, look for a set with only two wires, unplug it and the end that is hanging down, Take a small paper clip and stick it in the two prongs and then turn on the ignition (but dont start it) watch your check engine light it will flash.... long flashes go up by 10's..... Short flashes go up by 1's...so LONG LONG LONG SHORT SHORT SHORT SHORT SHORT SHORT SHORT= 37 hope this helps. try disconnecting your battery cables over night. This usually does the trick. Also check your fuses to see if one is blown (blacked out when you pull it out). Then reconnect your battery and see if the light stays out.

Which scan tool do you use for check engine light on 1995 Olds Eighty-eight?
You can usually borrow, rent or buy a GM OBD code scanner at most auto parts retailers. Since OBD2 has come out, the old version has been called "OBD1", but that's not what it was called when it was being used. The 1995 Eighty-Eight is a crossbreed. It uses the OBD-II connector but it is an OBD-I system. It appears that OBD-II code readers can handle this but I'm not positive.
