Hello, I'm new here and I just got a Civic Si and I have it for about a week now. This is my first manual car, and I'm trying to learn. Since this is my first time driving a manual, I want to ask some questions for reassurance because I'm kinda paranoid. Ever since I took it out of the dealership, my driving isn't smooth (lugging, bucking, shalling, etc.) and I understand that because I'm new and there is a learning curve. Some examples is that I ride the clutch on the first day, tried to downshift several time without rev-matching, and up shifted the car when it's in a higher rpm, which all of these make the car jerk or buck every time (obviously, I find out first hand). After watching/reading more about manual cars and how to drive one, these are things I shouldn't do. It will cause wear on the clutch and the transmission and it's my fault (probably took couple miles out of the clutch). I'm an idiot I should have watch video before buying it but it was an impulse decision on my side when I went to the Honda dealership. I was looking for a new car, and I ended up with an Si after seeing how nice the Si coupe looks. Since there are people on this forum that has more experience, do you guys know how many miles it takes off of a brand new car clutch or trans. I also saw on YouTube and this forum about the break-in period of new Civic Si's. The car is at 180 miles right now and I'm paranoid that I didn't "break-in" the car and being an amateur I'm driving it recklessly without know about this. Will there be any problems with the engine or the power train if I don't break it in properly? After finding out about this and saw video of what you shouldn't do in a manual car, I regret getting the Civic Si now. I feel bad because I'm abusing the car. I should have just got a used or old manual car first before getting something new and learn on it. And there is like a chirping sound in the engine now. I google about it and it landed me on this forum. Apparently it's a problem related to the high pressure fuel pump.
