What the hell...
So I had a battery die on me today at h&r block took it in to have it checked and it had a dead cell... replaced the battery and car wouldn't start right up the first try. Started up the second time kind of hesitantly but did. Pulled out of the parking spot at kragen and engaged the clutch to go into first and it stalls. Started it back up and got moving clutch in again and stalls... repeats this for about 4 times and then drives alright but the rpm drop super low almost to stall. Have no idea what's wrong the battery alternator and starter are all good had them checked. Drove home let the car sit for about 4 hours starts fine but then stalls twice while driving... any ideas would definitely help

wrx/sti or rs? do you have a BOV, no recirculation of BOV kind of likes to stall the car when rpms drop...
try going over the vacuum lines, thats another place a lot of idle issues come from...
one thing that sticks out if it starts up fine when cold, that may be because the engine uses very few sensors to start up until it warms up and then uses combination of sensors to gauge how much fuel to spray. if you have an obd scanner try connecting that and check for mass air and o2 sensor voltages or readings?
im no expert thats just kind of where i would start, i have a OBD2 scanner if you want to try it out.

It's just a stock 2.5i... The weird thing though is it never had this issue with the old battery so I'm just kinda confused I've read that sometimes the fuel pressure could get screwed up and since I put a full tank of gas in it it's been fine the rpm still drop but not past the 500 mark
