I agree with everyone else, clutch.

If you are saying that you floor your accelerator without having the clutch fully engaged... well then that is a major problem... don't do that.. ever!
You should always engage the clutch as soon as possible. From the lowest RPM's possible. Unless you are launching your car quickly.. then you raise the rpm's higher before starting to engage the clutch.. but you always fully engage the clutch asap once you start... does that make sense??? Just get your foot off the clutch.... nuff said!

so is it ok that give it a little gas first then engage?? let's say around 1.5K RPM then engage the clutch. am I burning the clutch that way??
cuz when I do that RPM raise first then drop when I start accelerate. is that called slipping clutch? thanks..

This part is good.. it's what you want to do.. give a little gas... engage the clutch gradually... when you start to feel the car move... give a little more gas and fully engage the clutch

Slipping the clutch is when you get to that 'starting to engage' point that I just talked about and you hold your foot there while you press on the accelerator...

you usually only slip your clutch if you want a fast launch and don't want to spin your tires... or bog your car from the tires having too much grip.(all wheel drive cars have this issue)..
you can also slip your clutch to go slower than the gear allows.. when you need lots of torque and not much speed.. like getting up my driveway and into my garage..

You have to think about what is going on.. your engine is producing a LOT of energy when you give it a lot of gas.. that energy has to go somewhere. If it doesn't go through your transmission to your rear axle..then your clutch is absorbing all of that energy... make sense...???

I am glad that I am doing the right thing so far. Thank you!

Thanks for the link, but I've read all that before already, but for me I'd like to find some "live answer" when the actual question comes to me. the explanation above sounds like "burning the clutch". are they the same? Thanks!

That's how a bad/slipping clutch acts, from personal experience with my old car (although it took me 138K miles to burn that clutch). Even if you're not engaging the clutch, you will see your rpm's jump before it finally comes down, and you pick up speed. Congrats!! You've now experienced a slipping clutch! But since you're planning to change out your clutch, you'll notice that it won't do that again with the new clutch--unless you burn that one out too...
