i'm just concern about the low pressure i have it's a hair above the red and when i go full throttle it dont move ?? could it be the guages oh i also got a missfire! any help is welcomed

 

Prove your gauge and wiring is good by unplugging the connector from the pressure sensor. Turn the key to ON. The gauge should show max pressure. If it does, you might need to replace the sensor or you really do have an oil pressure problem.
I wouldn't be going full throttle until you prove it one way or another.

 

i'll try that tomorrow after work, since i know you have allot of information do you a picture of the sensor that i'm going to unplug just incase i have trouble looking for it



thanks shoebox!

 

Picture? Me? No, I have never seen it. Oh, wait. Here it is. j/k

 

Check My Post

 

i know for sure i dont have the sensor there i have a 94 camaro and just took off the intake manifold last week and painted and replaced the gasket to cure a oil leak and didnt see it there.

 

Then look by the oil filter like noted in the pic for 1993s.

 

sounds good i'll give it a try

 

alright just unplugged it and the needle went all the way up. i also noticed that in the morning when i first start the engine it's about 20psi after it's been warmed up drop's to the red and never goes up no matter whaT I do. so what do think i should replace first? also could that cause the missfire? thanks

 

Replace the sensor, first. They can act like that when dying. I assume you found it by the oil filter? I think some early 1994s may have had it there, unless someone moved yours. It won't have anything to do with a misfire.

 

do you have the part # , thanks for all the help. if that dont work i 'll post it later.

 

From my part numbers page:

1993 oil pressure sending unit GM p/n 24575127

[edit] adding:
1994-1997 oil pressure sending unit ACDelco # same GM p/n 10201491
I'm really not sure which one you have.

 

i just took another look at it and the oil sensor has oil on it like if there was a leak, i just fixed my intake manifold leakabout 5 days ago.
