Crx cable clutch problem

Does your transmission and clutch work perfectly fine, no noise or any problem? I can't imagine why the idle would jump from dis-engaging the clutch from the flywheel. When you do that, the transmission input shaft is no longer turning with the flywheel- it becomes stationary. If the input shaft had worn gears or a worn bearing, I suppose it could put a little load on the engine, make it work harder to maintain rpm's. So when you push the clutch in, that load from turning a worn bearing or gear disappears and your idle increases. How's that for a crazy solution?

Don't know much about crx, but I assume the computer controls idle? If it does, the ecu would have no compensation in idle speed for pushing the clutch pedal down.

I see this is an older post. I have a 90 Crx and was wondering if you still have the car and how you solved the problem?

for a simple answer, yes-it has to have sufficent line pressure to engage, and low levels will dramatically affect line pressure.

only an alinement tool from hire shop dont forget a new bearing should also be fitted

Either your clutch is not fully dis-engaging or the transmission synchros are worn. Check the clutch master cylinder for level and check system for any leaks if it is a bit low.

check the alternator

check the wire going to the clutch or tranny switch for power from the ignition switch if there is no power there the ignition switch needs replace

Have you adjusted the clutch cable enough to allow it to disengage the clutch ? try that first. Is this the original clutch?

I don't know much about cars, but I've got a service manual for your care in case you need one. It's BIG, 300mb.

Let me know if you need it.
