Coolant or gasoline mixed with the oil. The oil light will only come on when the pressure drops. Drain the oil and see if it contains coolant or gasoline. You can smell the gas in the oil. Water will settle to the bottom.

It is probably a vacuum leak. that model doesnt have a carburetor, it has fuel injection. and whining is usually a vacuum leak. it also might cause the engine to "lope" at idle or for it to "surge" when you hold the accelerator steady.

None, it might cause oil to spill on your engine or inside of your hood, or a dash light might come on.

There are pages and pages of things that can turn the check engine light on. You need to have it checked for codes to know what the cause might be.

It might be that you did not tighten the gas cap enough.

You can tell if the transmission, in your 1998 Chevy Malibu, is going bad. If there is a whining or clunking noise. The transmission might cause your engine to install when you are stopped with your foot on the brake.

If the fuel pressure is too low that might cause the service engine light to come on and , since there would not be enough fuel pressure, might also cause a sluggish response. That could be caused by a clogged fuel filter also.

Your bad muffler might be part of the reason your check engine light comes on. Usually, your bad muffler causes something else to go wrong and that causes your check engine light to come on. Problems cascade.

Is it a fish smell or a rotten egg smell ? FISH SMELL COULD BE A BAD HEATER CORE, THIS WOULD CAUSE YOU NOT TO HAVE HEAT IN THE CAR , BUT IT MIGHT NOT CAUSE CHECK ENGINE LIGHT TO COME ON UNLESS MAYBE CAR IS LOW ON COOLANT. ( THERE MIGHT BE A LOW COOLANT SENSOR TO TRIGGER CHECK ENGINE LIGHT) ROTTEN EGG SMELL COULD BE A CLOGGED CATALYTIC CONVERTER , WHICH WOULD CAUSE THE OXYGEN SENSOR TO TRIGGER THE CHECK ENGINE LIGHT, BUT IT WOULDN'T CAUSE THE LOSS OF HEAT.

Several things could cause the 2001 Impalas check engine light to stay on. Since so many things could be wrong, check the computer codes for any leads on possible problems.

The whining could be related to the alternator. Does the car have any electrical problems such as the battery drains and dies while car running, are your belt(s) tight? in good condition? It might be a belt tensioner or idler pulley that is causing the whining.

It might be that your pcv valve is plugged or the egr valve is sticking.

The stop engine light might not come on on your N14 Cummins when the switch is off.

you might have a bad ground connection. Check your RCA plugs behind the head unit. They may be in the input instead of the output. This will cause feedback in the speakers.

Hey Ben==Have the engine tuned up and have the motor and trans supports checked. GoodluckJoe

My 02 liberty check engine light has blinked in the past. It was because my battery needed to be replaced. Count the number of times it blinks and search for that blink pattern online for better information.

You need to have a diagnostic check done by your dealership or you mechanic. When the light comes on again drive to one of these facilities and have this check done. It is worth the money.
