Default jdm obdII b18c idle problem...vss...iac...

i STILL have a idle problem with my jdm obdII b18c in my 97 civic hatch. not throwing any codes. doesn't idle down when warmed up, when i restart the car it does. when rolling ONLY, the idle jumps to three thousand or higher, then doesn't come down until i come to a complete stop. this results in a non-existant deceleration. this really bothers me. once in a while, when i'm in second gear and coasting, there is a deceleration "blip" and when it does this, the headlights get bright, then dim when the deceleration stops. tried three different iacv's, still did the same thing. here's the weird thing, when i unplug my vss, the problem goes away, of course my speedo and vtec resultingly don't work. i tried three different vss's and still did the same thing. what is the deal here, no one seems to be able to give me any ideas. and before you tell me to check my fitv, i don't have one, it's obdII. please, please help.

Yeah Josh needs some help here because Im sure not helping out any either. We have pretty much tried everything except for taking the intake manifold off the car and putting another one on. The car runs great but just does not want to decelerate while driving unless you come to a complete stop. He can be driving down the street changing the gears and its like he is speed shifting because the rpms will not drop when he lets off the gas and presses in the clutch.

It was the wiring on the MAP sensor this whole time and he fixed it tonight. 2 of the wires were crossed.
