help! i dont want a ricer

I know there's something friend wrong with my car. I'd prefer to get my /6 to just run better an figure out wits wrong. But I feel like wen I take it to a mechanic, they aren't gonna find anything wrong. I need it everyday an can't afford to have it stuck at the shop for a week an I feel it's a lost cause sometimes. I know I can get it fixed, and trust ne the 360 is the last thing on my mind for the car. Just would feel like I'm throwing away money putting extras on the /6. Idk i get ahead of myself a lot cuz i have such big plans for this little thing and im young an impatient! Haha I sometimes wish I had a mopar guru at the local shop or something
