Oil light and shake

[chelley]

My 2004 dodge neon se has an issue where when its at normal running temperature, and i am at a stop, the oil light comes on until i press the gas again. The oil level is correct and iv kept up on oil changes. I believe it may be the oil sending unit, however want a second opinion. Also when im in gear and im stopped, the car shakes pretty hard….I have replaced motor mounts which did help , however it still shakes pretty hard. I dont know if its idling to low or what but i need some help.

The oil light could be coming on due to the low rpm
which will slow the oil pump. The car could be misfiring.
You may need a tune up.

The only way to know what the oil pressure is, is to install a pressure gauge and measure it. Either that or just replace the sending unit and cross your fingers. I just had the same problem on my Caravan and it was the switch. I can uncross my fingers now.

Rough idle on Neons is a common problem. There is a procedure to adjust the engine mounts to minimize the vibration but it’s been a while and I forget most of the details. (sorry). You might find it by searching the net or by finding a service manual that explains it in detail.

First step would be a tune up. See if this helps with your rough idle condition. As stated above, there may not be an issue with your switch, but RPM’s are dropping too low. With the oil pump being engine driven, it must maintain idle or higher to deliver the proper oil pressure.
