crank car, engine stays reved??????
2001 honda accord ex, 2.3l auto
What would cause the engine to stay reved?
I changed the lower heater hose, and broke the distributor. About to replace distributor now.
Could this staying reved be caused by the distrubutor or did i knock something lose maybe?

It may have to do with the distributor.
Your 2001 Honda ECM uses input signals from different position sensors (CYP sensor, the combined Crankshaft Position and TDC sensor), which then sends a triggering signal to pulse the igniter, etc., etc. ... it affects ignition timing related to idling.
The Cylinder Position Sensor (CYP) which is part of the distributor body, the combined Crankshaft Position and TDC sensor (located just below the crankshaft, fastened to the oil pump housing; see link)
Honda-Tech - View Single Post - bad crank position sensor??? i need expert help!
Also see, the attached excerpt pic. from an earlier model year Honda service manual regarding ignition timing control; but, the basics are the same.

Excessive idle speed is usually caused by an intake air leak; vacuum line or intake manifold leak, PCV hose disconnected, brake booster vacuum hose disconnected. Suggest a close check under the hood.
Distributor timing might have an impact if grossly out of timing.
good luck

I believe on your 2001 Accord, the spark timing is set by the Crankshaft Position Sensor (fastened to the oil pump housing); so, timing is not adjustable by turning the distributor. Just try starting it up, if you haven't yet.

x2 on the crank sensor. I had a 1998 and the distributor didn't even have slotted mounting holes.
If you were to use a dremel to elongate the distributor mounting holes and twist the distributor, you probably couldn't even change the timing if you tried.

Thanks guys... So the distributor has nothing to do with timing correct? I just pop the new one on and go?
assuming misfiring
