[Presto]

I did a compression test on my ka24e, I got exactly 120 across the board and cylinder 3 was just like a tiiiiny bit under like near the next notch down,

I’m a noob sooooo I forgot to press the gas when I did it
-Spark plugs weren’t taken out but they were disconnected as well as coil and fuel relay

EDIT: I just went back outside and pressed gas down, all spark plugs out, let it crank 5 times, every cylinder reading exact same 120

-I’m using a $30 compression test kit from harbor freight, the brand is Pittsburgh. Car probably has a vacuum leak somewhere as it only runs good when I cover the intake with my hand otherwise it’s rough idle, also I’m not sure if the car was totally warm as it was running for maybe 2-3 minutes before I tested

Should I be worried about engine swap right now? Or is it cool for me to buy more parts to get it running better
