SES light and oil pressure gauge spike

so the SES light in my 87 IROC will come on and my oil pressure guage will spike but nothing happens to the car, everything seems fine and it only comes on occasionally. would my gauge just be malfunctioning?

Re: SES light and oil pressure gauge spike

It could be your voltage that is spiking. What code is getting stored in the ECM?
