  2. lx rev drop and slight vibe

    Mechanical Problems & Technical Chat
    So at stoplights My 12 Lx sedan will idle perfect but sometimes drop 100 rpm and start to send a small vibration throughout the car. After a min it will go back to normal and idle great. The needle never dances. Do I have bad fuel? That is what I am thinking.

    ECU Tuning
    Well, I have been doing a good job of not spending excessive amounts of money on my Si, but I am intrigued by FlashPro and the tuning services offered by VIT. Even though my engine is stock and will likely remain largely stock, I would like to know I am getting everything out of the engine I...

    Drivetrain Problems
    Hi, my Si has about 8K miles on it. Over the last couple of weeks my car has not had rev hang at all. I am wondering if it has to do with the extreme 100 degree temps in N.C. Anyone else have a similar situation or am I just lucky?

    Drivetrain Problems
    I am a new 2012 Si owner, and I am not new to manual transmissions. The only drawback could be that I learned on an Audi S4. The car has 700 miles on it. I have seen 2 persistent mentionings; Rev Hang and 3rd Grinding. Rev Hang: I have seen so many definitions of why this happens and what it...
