Low idle and jerky low RPM acceleration

Low idle and jerky low RPM acceleration
My idle has been really low (since I bought the car) although it has never died, I've felt it get low enough to where I thought it was going to die. With the A/C on, it idles where it normally should. The idle adjustment screw has never been touched so I'm thinking it's related to the jerky acceleration I'm having.
The problems are:
Lower idle than normal...i think?
Jerky low RPM acceleration until after 4,000RPM top end hauls butt.
The problem is worse if I push the gas pedal too much at lower RPMS but if I just barely give it gas, I don't feel it.
So far I've checked and adjusted the timing and replaced spark plugs, fuel filter and made sure the cat. wasn't clogged.

The fuel filter is new but my fuel pump sock might be dirty I guess or the pump could be going out. The spark plugs looked the same but they were rather white and not the perfect tan color I like to see.

The CEL is on but the code is P1457
I did jump the service connector.
I'll clean the IACV next.

The problem has always been there since I bought the car but I have checked codes 3 times and always checked out the be 1457. I still need to fix that too but I don't think it would hurt performance... just prevent me from getting an inspection?

heres a few other things that MAY be it. Theyre a fairly cheap fix so id start with them, if in fact it is not the CEL. Change the spark plugs/plug wires, dizzy cap/rotor, fuel filter, check the IACV (like RonJ said, its in the DIY section (i wrote it)) and the Fast idle valve

GReddy_Civic has some good tips; however, the 2000 Civic doesn't have a fast idle valve.
