I just swaped a sohc zc into a 91 crx hf I am using the hf tranny and for about a day it was all going fine but then sounds like something is hitting around in the tranny. when you rev it it hits around faster and when you hold in the clutch it slowly stops hitting around. so i pulled it in to check it out and let it idle in neutral as i was looking around and all of a sudden it just shuts off. now the only way it will start and idle is if you hold in the clutch. whenever you put it in gear and let go of the clutch it just shuts off imediatly. HELP ME PLEASE!!!!!

 

Did you install anything ? Like the clutch or flywheel ? If so did you install everything correctly ? Did you install the clutch disc the right way ?

 

i installed the flywheel, clutch disk, and pressure plate. it was running good for a day so something must have happened.

 

Did you use lock tite on any of the bolts ? Did you torque them down to the correct spec ?

 

i used an impact wrench to tighten them down

 

No thread locker ? I would take it all apart and inspect it before something else happens.
