Hi everyone. I have an '01 2.3L LX ULEV engine. Between 0-50 mph when I let off the accelerator the RPM's will drop quickly to just above 1000 then spike back up to where I believe it's supposed to be(1500-2000 at 45 MPH). This is my first Accord, not sure if that's normal. She will also drop to about 500 RPM(~rough~) when at idle during the the warm up period when I first start it up. Although that warm up drop doesn't happen all the time. Any feedback will be greatly appreciated. Thanks.
