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.

I know its kind of out of the question, but maybe you should convert it to obd1, and see what that does?
Sorry i cant help, im not very helpful when it comes to motor problems.

i had a similar problem when the tps was not adjusted right. It's probably not your problem but check the sensor in case

i've adjusted the idle screw on the throttle body and that doesn't fix the problem. i've tried three different iac's all of which work fine on my friend's cars, none of them fixed the problem. i have tried different adjustments of the tps, none of which fixed the problem. this is why i'm asking on here, because i have run clean out of ideas. i really appreciate the replies though. thanks. keep 'em coming.
