So I’ve been having some problems with my cat. If I got anywhere from half to WOT under like 65 the car would stall a few times in 3rd before it would upshift to 4th and continue on. On my way back from scheduling an appointment at the dealer for it it finally gave me a P025A code. I’ve seen a couple other posts about it but nothing similar to the issue I’ve been having. Just wondering if anyone else has noticed something like it? I’ll try and get a video of it posted here soon

The obvious first guess is the fuel pump is going bad.

Of course, it could also be something electrical or a problem with the PCM itself. This is one of those things where you'll likely have to take it for a proper diagnostic. Codes are all well and good, but a good mechanic or the dealership can read the historical files and/or view all the relevant live data to see what component is causing the issue.
