GMH94Z28

I have a 94Z28 and I have noticed that my oil pressure gauge seems to kind of jump up and down if I have it at lets say doing 45mph, Also when I am sitting in traffic at idle in drive it moves down right below the last line before the red zone. What do you guys think it could be? Thanks in advance

I got the same problem.... I hope somebody has the answer.....

Oil Pressure Sending Unit possibly... sits on the back of the block behind the intake... I can get a PN for you later or maybe if shoebox sees this thread, he'll most likely have it.

94_Camaro_LT-1,
Would that cause the guage to move like that? Thanks

Yea when they start to go, your gauge will start moving around or sometimes not even give a reading at all...

I don't mean to hijack your thread GMH94z28, but what is everyone's oil pressure usually at during cruising and idle?

A search should find lots of info.

my car does the same thing, I read a post about this probably less than a week ago someone suggested that it might be bearings going out and the sensor getting old. You should find it. I know nothing so don't listen to me but my car runs above the middle mark and then when warm and idling it drops just below the 1/4 mark just thought you'd like to know.

Is there any way to check the sensor?
