Limp Mode/ Service Stabilitrack

[Vettecityman]

My 2010 SS auto has gone into limp mode several times over this past weekend. So the 1st time I shut it off waited a couple of minutes and tried it and everything was fine. 1hr later same thing. Get her home and looked her over and noticed that the oil pressure is starting to get lower at idle. Checked level etc... everything was good and clean. Started her up again but this time I had my normal 50'ish lbs of pressure. Drove her an hour down and back the next day... no issues. Sunday no issues all day then limp mode again. Took off throttle body and cleaned it. She was fine most the day but did it again, oil pressure low but no waring, and 200°+ before I noticed. I'm thinking I have several issues but idk. All she has had done is a cold air, headers/ no cats and BMPR 3" to the tips out the back. Thanks for any help in advance.

Limp mode many times is related to the throttle body. You need to pull dtc's. When you say low oil pressure you need to be more specific. What PSI as what RPMs are you considering low? Was is particularly hot this day?

Well it usually stays in the 50+ and here lately she has been 30 or sometimes lower on idle. It has been somewhat warm but not insane. Mid 80's outside. So these are my codes. I seen everyone talking about cleaning them so I
removed it and cleaned the TB so could it itself be going bad? A couple of the codes were no communication with TB or something similar. I had to turn the key on to the car while the TB was disconnected.

That is a lot of codes. I would clear and start over if you had turned the key on while things were disconnected. I wouldn't consider 30psi at idle on a warmed up engine low oil pressure.

First thing I would do is to buy/try a new battery.

With all the electronics throughout our cars now, they are VERY sensitive to voltage.

When a battery starts to get wreak or die, it can and will have erratic symptoms all over the car.

That's a whole lot of codes. I'm guessing loss of compression in one or more cylinders. Could be a spring / valve problem, could be a damaged piston rings, or could be a faulty spark plugs, or plug wire. Also could be a slightly bent pushrod. Have you taken the valve covers off for a closer look?

[Vettecityman]

Well I haven't looked under the covers because like Smitty said it was all fine when it sat for 10 to 15 minutes. I think I might have several issues at once. My battery is 2 months old. Like you said HDRDTD said I had gremlins all over. I had a cheap autozone scanner that pulled the codes but I tried to erase but it wouldn't and said permit next to most so idk if thats because I didn't have a CAN line or something. She has 140k + miles on her so I'm thinking that I will just nip a whole lot of things in the bud. DOD/VVT delete ( even tho I was hoping to try and use that to my advantage in some way. VVT that is.

Perhaps dirty fuel injector occasionally clogging, or a damaged spark wire, or a bad coil pack? I just changed the plug wires on mine. My Camaro has 138,000 miles and the plug wires were in bad shape.
Maybe a bad spark plugs. You could easily pull the plugs and look for damage. They tell a good story if what's happening in the cylinder. Coat in oil, burnt, etc.
