i swapped a built d16z6 into my 94 coupe and ever since the swap u push the clutch in and the idle dies down and sometimes dies but as soon as u let the clutch out the rmps goes back up and everythings ok what could cause this

 

same thing happening to me but doesnt die but says its at 0rpm ( i always thought maybe my tach is just off)

 

nah my cars not off u can feel it die down and wants to stall out and sometime it does/?

 

um also try see if spark plugs have oil on them, just a guess cause my car would die down sometimes because of that (i thinkk)

 

is ur clutch possibly going? If so it would be like letting out the clutch w/o giving it gas (when in gear). Does it happen when the stick is in neutral? (not neutral by way of clutch)

 

its when ur at a stop or at a roll and push the clutch in wether its in gear or not

 

so if you just start up you car (in neutral), leave it alone, let it warm up, go outside (or garage, whatever), and get in, and step on the clutch (nothing else, no AC, heater, radio, etc.), the RPM's go low and sometimes stall out?

 

yes thats correct nothing else on doing nothing else not in gear or anything just pressin the clutch

 

It could be your throw out bearing.

 

anyother ideas

 

highly doubt its the throw out bearing...

mine does it to but not as bad as urs...

same thing when u turn ur lights on, ur rpms drop a little or pump ur brake, rpms rise a little???

 

It could be your MAP or TPS sensor, this would cause it. Check codes.
