Re: 86 4kq Low Oil Pressure

[quattro@rogerswave.ca]

I had the same problem with my 4kq.
There is a oil pressure system warning system that sounds a buzzer and 
lights the worning light over 2000 rpm in case there is a problem 
with the system itself i.e. short in the wire to the sensor or a bad 
sensor.
If it only comes on over 2000 rpm and you can drive all day below 
2000rpm without it going off it is the more likely couse.
Chech all the connectors and sensors.
HTH.
