hello guys, I had my s13 sr blacktop for a few months now, and recently it started to act weird.... it turns itself off.

Here is when and how it will do turn itself off. It happens when I left off gas, cluth to netural and brake than the rpm drops really really low and than the engine turns off. Sometimes, rpm will bounce back, and if i keep on gas, it will stay alive.

bad O2 sensor? I can't think of anything else, Please help. Is very very scary when you shift to 2nd during a turn in busy intersection and the car turns off ,power steering goes out ,and there is an angry hummer with spikes around the corner waiting for me to crash into it...

My KA dose that because it has mad low compression, 60psi on cylinder 1. If you have a compression gauge you can check that for free.

^ I also had good power. I made 114 hp on a stock ka about 2 weeks before it got really bad. I checked compression and it was 60psi on #1, and the others were not to good either.

with the sr i heard if you run a bov that does not recirculate it throws the computer off bc its not getting the extra air and its flooding so it starts to bog and shut off ... im having that same problem i have a non recircutating bov but let me kno about the compression test and let me kno then ill check mine

I hope your problem is simple, I know the symptoms you are describing match my engine perfectly.
