I have bleed brakes and other clutch systems on other car I have owned and have never had this issue before. What makes the Miata any different. I do appreciate the help that everyone has given me. I am just at my wits end. At this time I might just want to take it to a mechanic and have them do it! I just want to drive the car!!! LOL
how are you testing if its bleed or not?

I know after a bleed, my pedal always "feels" less than adequate. Hell, ask Dntlift about bleeding his brakes at the track this weekend and thinking it had air in it.

Is the clutch operating normally, or does it not disengage on some occasions or are you making that conclusion based on sitting in the driveway with the car off?

The way I am testing it is. I start the car and press the clutch in and put it in gear. With the clutch still pressed to the floor and the car parked I then wait to see if the clutch will engage by itself with out myself lifting up on the clutch pedal. It will act like all is good but after about a minute the clutch will slowly engage by itself.

sounds to me like you have a leak somewhere. there is a rubber line on the firewall that goes to the transmission, may have a crack in it.

Its the line connected to the hardline loop that connects to slave cylinder.

Its pretty short really, but it will get hard and crack after some time.

I suggest you replace it with one of the longer clutch lines that delete the hard line that is coiled.

I think 949 sells them for $24 or so.
