1999 Honda Civic 91,000 miles

Hello:
Not sure what to do. I bought a Haynes Repair Manual for my vehicle and I see what the manual is telling to do. I don't want to take the wrong part off and screw it up more.

When the car is in a parked position with the engine running, it idles up and down. When I drive it, it sounds a bit loud. Any help you can provide is greatly appreciated.
Thanks,
Darryl

Hi dwoodard,

P0505 = Idle control System Malfunction.

P1337 = Crankshaft speed fluctuation.

Get the idle control system checked first.
