What do y’all think? Tried cleaning maf and cables seem ok. Around the same time this started popping up I also had my sub amp go into protect mode... runs fine
Yes, high probability of a bad ground. How many watts power total does your stereo system consume? It is also possible that your stereo is pulling your PCM power voltages low which confuses it.
How close does your stereo system get to your PCM? Big stereos generate interference that can also cause some of these things.

How many amps does your alternator produce?

about 1800 max total. PCM is under hood, system is opposite side starting at battery.
The other amps work fine for the tweets and mids. Verified the grounds for the system in the trunk and by battery. Also if I disconnect the amps and stereo from power and ground problem persists even after multiple clears.
im wondering if something came loose behind the amp rack in the trunk I can’t see. May dig into that next.

first question was how many watts does the stereo consume. And that’s what he answered
Sorry yes 1800watts max but I never turn it up. And alt is a stocker 140 or whatever and battery is a red top. I plan on getting a 300plus alt and a kinetic battery soon
