  1. Are these normal vacuum readings? Vacuum leak / MAF issue?

    Mechanical Problems & Technical Chat
    I'm trying to figure out whether or not I have a vacuum leak on my '12 Civic LX.. been having a super rough idle, random shaking and vibrating. Acceleration is not good, lots of hesitation picking up speed. No check engine light. I bought a BAFX Bluetooth OBDII scanner and the Torque app to...
  2. Grinding(?) noise at 4000-5000rpm

    Mechanical Problems & Technical Chat
    So, short story first: I just installed the fkx strut bar, I tightened everything down securely, and torqued the nuts to 44lbs. Afterwards, I took it for a drive, radio off, so I could listen to make sure nothing was going on. That's where I noticed the car would make a grinding noise under...
  3. Very Slow Acceleration when the car warms up

    Mechanical Problems & Technical Chat
    Hi, I have bought a civic 2013 from my friend. It's still under warranty. I am facing an issue regarding car performance. When the engine is cold, or say first 15 minutes of driving, the acceleration is literally like a sports car. But I feel a major difference in acceleration starting after 15...

  5. "Chugging" during hard-ish acceleration

    Drivetrain Problems
    This is no big deal, and I don't think its a problem, I was just wondering if anyone else noticed it. In the last month or so I've noticed kind of a chugging feeling when accelerating at about 3/4 throttle. I really only feel it when the car is revving pretty high for a few seconds. When it...
  6. Engine "Stall" During Low Speed Acceleration

    Drivetrain Problems
    If I am slowing down, to about 10 mph or less, and need to accelerate quickly, the car will sometimes "stall" for about a second before it downshifts and takes off. The "stall" is not a true engine shutdown, but is a loss of all power. It happens almost always when I am turning left. It's not...
  7. Sudden Acceleration?

    Drivetrain Problems
    She came home to tell me that when she was driving to work yesterday going 40 mph on a flat road that when she was coming to a stop light she started to break when the rpm's jumped up to 3 and stayed there so she pulled into a parking lot put it in park then it jumped back down. She found it...
  8. Whats a good bolt on mod for the Civic SI ?

    Si Only
    With my older Civic, i found Spoon Sports and T1R to be my top favorites for performance. I used some Injen parts in the past, but i ended up selling them within weeks of buying it. What are your favorite aftermarket performance brands?
