Loss of oil pressure when cold

Vodkapocalypse · 11-09-2021, 09:48 AM

Hey guys! New Camaro owner here, 2019 Turbo. I noticed this issue last year, but when spring hit, it stopped happening, but now its back. When it is cold, and I am idling, my tachometer starts to fluctuate and the car shudders. If I come to a hard stop, it seems worse, and the car has shut off completely once. I went through the diagnostics on the steering wheel, and oil pressure is corresponding to the fluctuating tachometer needle. When I asked about this at the dealer last year, they told me they could not run diagnostics unless I removed my aftermarket CAI. Is this any kind of common problem? I am thinking I need a new oil pump. Any advice would be greatly appreciated.

Sounds like you have a cold idle stability problem, and the drop in oil pressure is secondary to drop in engine revs.
Why not reinstall the stock intake and see if the problem resolves? And then, if it persists, the dealer will help you.

Do you still have the stock intake? I am going to guess that there is a 50% chance that the intake is causing your idle problem. There are a bunch of issues that pop up when you just replace all the factory stuff with a clean flowing tube. I have seen it.
