>Bought a 2010 Subaru outback 3.6i Limited (not really sure if that matters but I figured I'd get the full details out there in case it helps with diagnosis)
>car seemed to be perfectly fine, had a clear carfax, recorded service intervals, etc etc
>Drive it for about 2 months with zero issues
>Now, sometimes when I accelerate from about 45-60mph, the car will "judder" or "skip", like someone is tapping the brakes or it's skipping a cylinder or it can't figure out what gear it wants to be in
>One time this happened my ABS and brake lights came on, and I had to pull over
>when I restarted the car, the lights were off and I didn't get any issues with the juddering for a little while
>Still occasionally happens, seems to be becoming more prevalant
>Cannot figure out what the fuck is going on and afraid to take it to the mechanics and have them slap me with a 5000 dollar bill or something

Please /o/, I need your help. Does anyone know what the fuck is going on? Could it be my TPS, or is it a bad spark plug, or is my entire engine just fucked? I'm at the end of my damn rope.
