hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck

SOURCE: Oil Pump light flickering + rough idle on 1996 Nissan Maxima

Sounds more like the Throttle Position Sensor or another sensor is letting the engine RPM's drop too low. When the RPM's are too low, the oil pump is not pumping enough oil.

Will a 1987 Yamaha riva razz start with oil light on while trying to start it


check the oil level.If it is a normal engine lubrication set up the it will require oil pressure to put the light out which means that as soon as it starts or during cranking the light will go out and it will start. If the oil light is an indicator of low oil level then it will not start until you put oil in the emgine . Check the switch for correct opertion.

1999 chrysler sebring low oil pressure at idle


It may be the oil pump. If the gauge is going up when the rpms increase it's probably not the gauge or pressure switch. If the computer senses the oil pressure is low it will shut the vehicle off to try to save it's self from catastrophic failure. Also it may start cranking longer before starting. Thats it building oil pressure before the computer will let it start. Make sure oil is full, clean & thick.

Knocking knoise under 1500 rpm


If your car has hydraulic tappets and low low oil pressure at engine speeds then it can make tapping noises. Oil pressure is needed to maintaine the tappets clearances, excessive cleaeances will produce noises.

If itis the 4 stroke version then are the valve clearences correct! if hydrolic lifters push them back in in a vice to re-set them (they use the engine oil) pushing the oil out then put them back they shoul adjustthemselfs after a miniute or two O.K.?

Yamaha 50 hp motor oil red and green oil sensor lights are on


The engine will self destruct if you continue to run it without the proper oil mixture. Some oil systems have to purged of air if ran dry. Seek professional assisstance.

The grinding below your feet is the starter,the oil light will allways come on when the rpm's drop to low.
This sounds like a vacuum leak,clogge EGR, throttle position sensor,or incorrect timing.

what is the temp when you say it is overheating?

Wont stay running with out the choke on


it sounds like you need a carb clean performed. the idle cuciut jet is probably dirty and that is the jet that supplies gas to the combustion process at idle rpm's. when you have the choke pulled out it is adding fuel and air so when you shut off the choke the fuel supply goes away. for the oils use yamalube 2 stroke oil for pre-mix and 10w -30 gear oil for your tranny.
