RPM's Dropping to Zero (P0103 - Circuit A High)
 

Hi All,

The issue:
I recently replaced my air filters and cleaned MAF + throttle body on my '04. After doing so my vehicle gave me a P0103 - MAF "Circuit A High" code.
Tried starting up the car and it started up and turned off very similarly to a SKREEM module failure. Was very worried until the car started for a 4th time. Wiggled the wire connected to the MAF sensor and the thing started right up, but the RPM's are incredibly low. Occasionally the RPM's will just drop to 0 and the engine will just stop running entirely.

My Troubleshooting (So Far):
I'm thinking that an electrical component somehow might have been damaged when disconnecting the MAF. Purchased a new MAF sensor + used an auto electrical cleaner to determine if it was the connector on the MAF itself, but the car actually performed even worse with the new MAF sensor. The RPM's rapidly fluctuate up and down + some engine shuddering reminiscent of a vacuum leak? I'd like to think I take decent care of this thing, but it's very clearly telling me otherwise haha. Very confused on how some routine maintenance has devolved into this big of a headache.

Has anyone experienced anything similar, or have any advice on where to start looking?

I was reading a post about a problem similar to yours. It starts off with a different code but eventually a P0103 shows up.
Here is a link to the thread. It's not that long and there's some good advice in it.
I hope this helps.
