00 dx civic just swapped jdm b16 and every now and then the car stalls whenever i'm about stop or slow down. so far i've only lowered the rpm but i'm thinkin it may be a computer problem. i have no idea. just lookin for some advice or an explanation.

 

You might get a better response over in the Civic/Del Sol/EL forum... we only deal with pre-1992 Civics (and CRX's) over here. But you might also check for a vacuum leak...

 

that's right, do you have a cell light? if so, then you've got crossed sensors somewhere. how about fuel? will the stock fuel pump feed a b16 without probs? how many miles were on the motor? a couple of people i know had that problem, I pulled off that sensor behind the intake manifold that has the 2 coolant lines running trhough it (i thinks its a IAVC or EAVC sensor) and cleaned it / the screen and the insides of it with carb cleaner. thats it or that could be your problem..... your idle air control valve, it allows your car to idle properly when your foot isnt on the gas peddle, even when it means slowing down. clean that thing with carb cleaner and give it a shot. like i said a couple of people brought that problem to me and their idle air control valve was mis behaiving (one guy had a crossed sensor with that valve).

 

im not tyring to steal your thread but the (EVAC) valve in my car is making my car idle @ 3000 rpm,we plugged the bottom part of the line up so it wont even work anymore.all it takes is carb and choke cleaner to clean it out?

 

hey phobia, 3 grand rpm idle = im quite sure your throttle cable isnt so tight that it moved the throttle body just a tade and are you positive you dont have a vaccum leak anywhere on your rig? one of my friends (92 civic ex, idle'd at 2500 after removing his turbo = turns out the vaccum lines the boost guage went into was open for business). pluggin the bottom of it, do you mean you plugged the 2 holesunder that thingie that allows the coolant to flow through? yes, all it takes is carb cleaner, preferably anything in relation to carb cleaner that will eat through gunk as you spray it, but after you reinstall the sensor assembly your car will be a little funny on starting until it burns all that junk off. if your positive its nothing but that vavle, maybe your car is doing that high idle because you blocked the coolant lines to ensure the vavle wont work anymore. try and un block them, return the vavle to normal operation and let us know what happens.

 

yup. it was the idle controll valve it was auctually broken into 2 parts.the sring and the plastic gromet thing were pressed up into there housing."there saposed to be toucheing.i have no idea how it happend but i replaced it with a new one and it is working now. it was causing a huge air leak and sucking it up. thanks for the help
