Car Tweaker

i have a 92 civic with a b18b1(98 ls) in it. After the car is warmed up and im sitting at a traffic light or something and tap the gas the rpms will go up like there suppose to, but when the rpms fall back down to idle the rpms go to low and the car almost dies out.

anyone have any idea what this could be?

thx dan.

does it idle perfectly fine? adjust the idle screw thats on the throttle back check the cable idle. mine use to do the exact problem adjusted the screw and cable fixed the problem

Is your throttle cable adjusted properly? Maybe tighten it up, see if it helps. it may just have some slack.

maybe time for a tuneup.

Clean out your IACV...two bolts on the front of the IM..unplug the sensor and the rubber hose.

clean it up and reinstall and see what happens

yea i already cleaned my IACV, if i brought the car for a tune up, what would they do that would stop the idle from dipping down like it does?

im no mechanic but my last car was a pos and had similar problems. fresh plugs, wires, etc. could help. might be fuel related. try replacing fuel filter or it might be something more like fuel pump.
