Pull the sensor off and clean it out. It is the 1 wire duwicky that sits above our oil filter housing. Pretty simple. Don't forget to clean the connector too. Prolly just got some thing stuck in there and that is what is causing the fluctuation.

Let us know if this helped.

Brake clean works great because it is high pressure and it does cut grease pretty well. Soaking it in some seafoam wouldn't hurt. (edit: seafoam would cost as much as a new sensor lol) I mean anything that cut grease will due. But definitely spray it out with Brake clean

Generally it just won't read correctly. No point in replacing just clean it out. Plus I think the one from your year may be more expensive. To replace an old 87 was only 5-10 bucks.
