hey guys im a new owner and am learning about the fd and i have another issue with it. everytime i press in the clutch the tach drops way down to the 0 rpm's and then it hops back up to around 900 to 1100 rpm's this i know isnt good. it also sometimes will drop to low and stall on me any info that yall have will greatly help me. I think it might be a leak in the vacuum lines but that means i have to replace the rats nest which i dont want to do. if there might be something im missing let me know i need help asap. thanks again.

 

Do a search on clutch switch.
Its an easy fix I used a spring from a ballpoint pen.
