I've got a D16Y8 in a 98 EX with around 155,000 miles.

My clutch was replaced with an Exedy Stage 1 kit. After driving it for around 2 weeks, I noticed that I would lose some pressure in the clutch pedal when shifting between 2nd -> 3rd or 3rd -> 4th gears. The pedal will go down at least halfway without any pressure and then have some pressure at the very end. After this happens, the pressure at the clutch pedal on the next shift will be higher than normal. So, I took it back to the shop and they bled the clutch. It was still doing this so I had them replace the master and slave cylinders. Everything was OK for around 2 weeks. However, this is happening again.

Any help will be greatly appreciated. I've spent so much money without any solution.

Thank you.....

 

I've read that a "sticky" throwout bearing catching on the collar of the clutch could give the symptoms that I am experiencing. Any feedback?
