$50 To help solve this problem 1999 trans am
390, turbo , 4L80e
Here's the issue I accelerate and at right around 5500 rpm the pcm does a reset with the swing of the gauges and the trip meter reset, also my wideband looses power and resets.
I attached a short datalog, frame 195 is where it does the reset, if you look at the afrs you can see how they drop down to 10 that's the wideband powering back up.
I'm thinking it's somewhere in the electrical, I datlogged the voltage and it does it everytime.
If someone knows what's causing this I will gladly paypal you $50. Worth every penny to get this resolve.
thank You

Did you check your battery connections??? Battery going bad??? My gauges in my Lightning will sweep when the battery is about to crap out. I know you are SUPPOSED to be running on alternator power when motor is running..... But if you have a cell going bad, it will cause all kinda of demons for sure.
