something is bad here..my shifting is ruff i grind third...and when im in gear i can still take it out of gear without pressin in my clutch...wierd...need info is it serious????again i was acceleratin fast hittin boost and like @ 5000rpm maybe....i hit the brick wall and te loud pop sound...then my check engine light came on...

 

Have you played with the clutch rod that's connected to your clutch pedal and master cylinder yet?
You should be able to get out of gear from 3-5 (I think it was, maybe just 3&4). 1&2, you should have to press the clutch in. Mine does it and thought it was weird too, but my clutch only has ~4k on it with new Redline fluid. Other DSMs out here do it too...odd, I know.
Have you checked your fluid level? Does it have metal shavings? What have you done so far?

 

well i changed my fluid looks good to the eye,,,i put a fidanza clutch and flywheel...but the instruction manual that came with the flywheel said to use only 95 model hardware dont know why u think that could have something to do wit it you think it could be a bad synchro in third...or maybe the master cylinder how could i check with out paying a costly mechanic....any info on the sputtering poor performance loud pop wall hitting maybe fuel cuttin dsm...

 

and also when i push my clutch in it makes kinda like a humming noise..like when u have no power steering fluid
