SOURCE: check oil light comes on in my 1994 olds achieva

In the oil pan on your car is a sensor that works the ckeck oil light. It is a two wire sensor that just unscrews. It has probably gone out, or hung up. It has a photo cell on it that can go out. If you replace it you might want to wait till your next oil change because you will lose all your oil. Good Luck

SOURCE: idles ruff when warm, like it has a miss and black

Are there any fault codes in the ECM? No "Check Engine" light on?
Black smoke means it is running rich. You should be getting Rich O2 sensor codes. Running rich is usually caused by the Mass Airflow Sensor. (MAF) This is located in the snorkel that connects the air filter to the throttle body. Make sure that the snorkel hose is properly connected to the sensor housing as well as the throttle body housing. (See Picture)88a7041.gif
Also be sure to check the reference voltage (VREF) to the MAF, MAP and TP sensors. It should be right at 4.8 to 5.2 volts. If it is low, suspect a shorted sensor. Note that several sensors are served by the same VREF circuit. I had one GM 3.1L engine that was running like **** and smoking black that had only 2 volts at the MAF. I started unplugging sensors to see if the VREF would come up to specs and found that I had 5 volts at the MAF with the Coolant Level sensor (in the radiator tank) unplugged. Replacing the Coolant Level sensor fixed the car. Any of the sensors could cause the same problem if it is shorting the VREF circuit.
If the VREF circuit checks out OK, Then I would Try a MAF sensor
If you are getting misfire codes, you probably have an injector sticking open.

SOURCE: Start up car check engine is on and idles way too fast

Check the throttle cable for slack. There should be about 1/2" slack when not depressed.
Also check EGR pipe and EGR for exhaust leaks.

Oil light comes on, loses power, stalls, restarts but engine very rough, oil level is fine but oil is very hot, smokes


Check for trouble codes. Smoke out where? out the exhaust? Do a compression test to check internal mechanical condition. Low compression would likely mean expensive engine repairs, no easy fixes. If the oil light comes on well before the engine loses power, have the oil pressure tested on a gauge. Low oil pressure could be a bad oil pump, worn crankshaft bearings, or a blockage in the oil passages throughout the engine, or a clogged pick-up tube and screen in the crankcase. How long do you want to keep whipping that achieva, Mark? Might be time to look for another pony !

I doubt it.
If the engine is cranking, the starter is working.
If the engine will not start, you need to know if you have spark at the plugs, fuel pressure at the injectors, and normal compression.

I have a 96 achieva the cooling fan only powers on at start up for a second then shuts off and does not come on again what needs to be replaced and where can I find this part under the hood?


check your coolant level. there will be a temp probe in your coolant system. if this isn't getting coolant on it (due to being too low), it may prevent your fan from coming on.

96 olds achieva wont start unless daylight running lights come on when ignition switch is turn on


You may have a key that has a transponder hidden in the plastic key head. If the security light is on, that means that you DO have an antitheft feature that is not working properly and is most likely causing your problems. Take a look at this link, it explains the security issue and some symptoms. Along with some DO IT YOURSELF solutions.

My 96 old achieva will start and warm up but the fan will not kick on how come?


Possibly no voltage at the temperature sensor in the radiator or the thermostat housing. Also check the wiring from there to the fan. If there is power at all these places then the sensor could be faulty or the fan motor.
It might just be not getting hot enough, go for a drive and then see if it comes on.
