300zx problem.

[SkateOrDie]

Is it normal for my 300's psi oil gauge to be at 60? A couple days ago it was at 0, yesterday at 20, now 60?! What's wrong? Also when I start the car it's at about 1500 rpms, why's it accelerated?

stock gauge? or aftermarket?

Does it stay at 1500 after it warms up?

[SkateOrDie]

It's the stock one
Nah it's at 2k rpms when I start and 1500 when it's warmed up.

oil pressure sensor is frequent problem on 300zx, mine would do the same.
Just changed it or install an aftermarket one.

Every car have a 'cold start' function. A valve give it more air so it idle higher for 1 or 2 min. It should be idling at 850 rpm when hot if its not, something else is wrong.

Buy yourself an Shop manual for your 300zx , you will need it :)

Idle issue could be several things. TPS, a vacuum leak somewhere, AICV might be acting funky

if your oil is cold, it might have a higher pressure because it doesnt move through your lines well enough

Remember, its not good to have too much oil pressure. A little pressure is fine, and it can fluctuate a little.
