Z broke down, I bought a new car
My Z was being extremely bitchy the other day, was sputtering under acceleration, was running rich, misfiring, and the clutch pedal lost all pressure. I got pissed off and decided to park the Z and buy a new car.
Good news is I have a brand new 2010 Honda Civic LX, bad news is I have a broken Z in the garage.
The sputtering and misfiring is due to A/F mixture and poor ignition timing, but the clutch is another story. I've got a Centerforce Dual Friction clutch in there now with the stock 4 spd and a throwout bearing from a 79 280ZX, per the instruction of MSA's catalog. The master and slave cylinders were replaced when the clutch was swapped, but I cannot get the clutch to disengage fully unless the clutch pedal rod at the master cylinder is adjusted completely out. I've tried toying with the adjustment at the slave cylinder but the clutch will still not disengage unless I have everything adjusted completely out.
Anyone have any ideas as to what could be wrong?

is it properly bled? I mean really well. and you need to adjust everything so there is almost no play in the clutch pedal, only like a 1/4 inchis what I usually go with. Also, your throw out fork is very possibly not on correctly. Or even you got a bad new slave or master and one is leaking and you just havent noticed it yet.

If you have the TO bearing mounted improperly on most shift forks you will have disengagement issues. and with a clutch as strong as a centerforce there's always a chance that it can pop the TO bearing back in.. BUT it usually bends them and you have to pull everything back down again.
Im not claiming to be perfect EVER.. ive done this a few time, umy final lesson was dropping my SM465 cast iron tranny from my chevy 4x4.. alotta work for a simple over site, try to see if it is like that with a flashlight, I am unfamilliar with the Z manual tranny and have no idea if you have enough room to peek.
and good luck.!

Well look at it this way man. Now you can take your time, and fix your 240z up like you want to. And not have to worry about keeping it running to go to work. Since you now have a dependable new car. You can worry about other things. Good luck man.
