So when you let out the clutch in order to start moving, the clutch doesn't grab? Your second issue (going into gear rough) makes me think you might have air in the clutch line or low fluid. Regardless, Exedy makes good clutches for stock-ish HP.

It only happens sometimes when i’m already moving changing into 2nd gear and up. i’ve asked a couple people about it and they say it could be a two-step clutch or something like that but i doubt it since it’s never done that. And also i hope that’s the case because for now replacing the fluid or removing the air could save me some bucks for now. andd you have any recommendations for a good fly wheel to go with that clutch? i was thinking an aluminum flywheel to cut some weight on a already heavy h22 motor, plus my intentions are to have a street/race car so i think that’s the better option???? i just want some more insight. )

In my experience, if your clutch is burnt up, it will be much more likely to slip in first gear because your car isn't moving. Once it's moving, the inertia is of it in motion is helping your clutch to keep your car moving. So if it's happening in 2nd mostly, I would suspect something other than a burnt clutch. Try bleeding the clutch line at the slave cylinder and see if that helps at all.

Exedy also makes good flywheels, I have their 8.8lb chromoly flywheel in my LSVTEC right now and I like it. Bear in mind that you're removing rotational inertia from the engine, which has advantages and disadvantages. You will have to rev the engine higher to move, and burnouts will be harder because there's less weight to shock the drivetrain with. The engine has to move less mass to get the revs up, so it will get there faster, but at the same time, once it gets there, it has less to work with, if that makes sense.
Personally I like it, but overall I don't think it is super helpful.

Too add to this on the lightened flywheel. The lighter flywheel is good for acceleration but worse for fuel economy. RPM and car slows down quite a bit faster with the light flywheel. I saw a 2-3 mpg drop in avg fuel economy with I replaced my 2008 Civic Si with the Exedy racing flywheel and stock clutch kit.

OK if the clutch is bad or the transmission is not in gear, the rpms will shoot up when you hit the gas but the car doesn't go.

If the rpms don't come up then there is a different problem. The check engine light coming on suggests you may actually have an engine problem. A bad clutch or transmission won't make the light come on.

^^^ That's true. OP, get the code checked first, then go from there. You should have mentioned in the original post that the check engine light comes on, that's literally your car telling you what is wrong.
