Re: 4kq low oil pressure light- help!

[DGraber460@aol.com]

Very common problem with CGT & 4k cars. I have had 2 85 CGT's do exactly the 
same thing. They use 2 pressure senders for the oil indicators. One unit is 
for both above & below 2k rpm. The other for is for the gauge. So I have been 
told. Any experts feel free to correct. I have not been able to sort out 
which circuit is for which. When you back of the gas your RPM will drop below 
2k and your buzzer will go away. Replace the high end sender (if you can 
figure out which one that is, let me know as my Coupe is still doing it) & 
your light will behave as it should.
Sorry I can't direct you to the exact unit, but don't worry about your motor. 
Its fine.
