Awesome thanks for explaining that. I'll try doing a log tonight or tomorrow (and hope it doesn't stall on me again).
I'm not sure what exhaust I have rather than that the muffler is magnaflow, it was on the car when I bought it. All I know is it's a big rusty 3" pipe with no cats or anything, with a probably overly large downpipe (4" I think).
Also for when I do logging, can I do the logging right after the engine warms up, or do I have to log it while it's bogging/trying to stall? Because I can drive about 5 miles with it running fine, then after that the it starts having problems.
