Idk what’s up with my car

[Brose69]

So I got a 2008 ford mustang gt/cs back in August last year, it had a tick in the cam. So last week I changed the cam and the rocker arm that caused the damage. Now my car is in limp mode and I can not figure out what the problem is it's saying that the mass air flow sensor doesn't have enough power in it and the o2 sensors in say they don't have enough air for the mixture and I'm at a loss.

The error codes: P0102 P2196 P2198

What are your fuel trims doing?

Have you gone over all of your electrical connectors? Anything you have touched, look at it again.

Did you replace both cams? Phasers? New phaser bolts? Do you have pictures of your timing marks?

I honestly don’t know about fuel trim.
I’ve checked all the connectors but I’ll check again I didn’t see anything disconnected or moved out.
I replaced both cams, phaser bolts, kept phasers the way they are I didn’t see anything wrong with them I don’t have pictures of the timing marks I just physically marked them with a sharpie

Clearly seems like a fault with the MAF. I would check the wiring, connector and sensor itself to ensure it’s getting signal, as that would explain the low voltage code and the stuck rich codes.

An unplugged or faulted MAF will force the car into limp mode.
