There is NO Black on my car... And I am Not missing any plastic on my car, the plastic in/outside my car is "Gray"

As you can see there are letters ABS on this piece of plastic. Is measures 4 inches by 4 inches by 5 inches give or take.

[Does this belong to my car?]

I have a 91 Legacy LS, its Gray with Gray interior. I opened my car door today and this BLACK piece of plastic fell to the ground. I dont have any "Black" plastic in my car! Do you think it belongs in my car somewhere? Or do you think someone might be tampering with my car? I have no idea why this would be stuck in my door??

Is your handbrake not on. You changed the rear rotors, can you spin your wheels freely when lifted from the ground? 

On the other hand a AWD car should pull through the handbrake.

Handbrake is not on, yes you spin the wheels freely when lifted from the ground.

What is the speed limited by, maximum engine RPM or not enough power from the engine?

I wasnt even thinking the tranny was going until my ex came by and said it probably was, but before I sell for parts or junk I hope it isnt a $10 part! I'm not sure if I am understanding the question "What is the speed limited by" The day before this all happened my motor was shaking very bad, then the next day idle was fine. It doesnt seem to get power when you gas it but then again it doesnt shift well either if that makes sense..

Hi Guys I hate to make this my first post but I need your help!

I have a 1991 Subaru Legacy LS... 3 weeks ago I just put ALL new brakes on, New back rotors, new muffler, new master cylinder, new tune-up. Just a few days ago my car was on high idle and when you step on the pedal it wont go past 30mph do you think it might be the tranny? The very next day the motor sounded normal but still wouldnt go past 20-30mph but got hot and engine light came on. Transmission fluid did smell burned and looked brown. I only put 400 miles on my car in 8 months, I baby my car how could my tranny go?? Right after I hired this guy from Craigslist when he put on my MC, my brake pedal is very slow, hardly any brakes! I think I might have to junk my car, I cant afford to fix it anymore, but I need a car, both my son and I are on disability and we have to get to the doctor. What could be wrong? Oh.. this high idle happened 1 time about about a month ago!
