would it be oil pressure sending unit if some days oil pressure stays at zero and then some days it goes up and down randomly regardless of speed? sometimes also it only goes up when i accelerate. the other day it stayed at 40 the whole time i was driving, but lately its either fluctuating randomly or staying at 10 or staying at zero. i just had an oil change and its still doing it.

Maybe, but it may be a loose connection at the sending unit. JMO

i have wiggled the connection at the wiring going into the sending unit thinking maybe it was knocked loose duing an oil change but no difference... im just wondering, a friend told me the sending unit but he has been wrong and cost me money before.

The one time in my life I used a filter wrench (I was a lube tech for a year). I smacked the sensor on my 95 and it did the same thing. Please note you can buy (or exchange) 15 of them and they will all read different. Factory oil sensors aren't that accurate. My new one reads 60 at idle. Talked to many people who knew more then me before I believed. Some times I'm stubborn.

yeah i figured thats what it was, i just wasnt sure if somebody maybe had another idea, but i think i saw them for like 25 bucks so no biggy.. looks simple enough to change, its weird tho cuz its not in my haynes manual.. i think u just screw it off and screw in the new one? can anyone confirm if thats how its done?

just be careful you don't cross thread the new one when installing it
