Hello All

I couldnt find anything so here it goes, I have a Civic 2000 Ex 2 door Auto I've notice that I have to floor the gas so the car can wake up and go I just to be able to slightly push the gas and the car will speed up but not anymore. I notice that the Idle is uder 1000 rpm maybe 300rpm when Im in a light and it feels like its going to turn off maybe that has something to do.


Please help

Ritchie

did you check your throttle body cable?

do you have a "Check Engine Light"? you sure your idle is at 300rpm? and not 750?

I actually tight the cable a few months ago cause I tought that was the issue and I just checked it and seems just a very litle loose. maybe I need to tight that again

BTW how do I get the idle to 1000 with the cable or there is a screw in the IAC valve

thanks

you should be able to see a screw by the throttle body.

the throttle body connects to the intake manifold, you're on the right track. locate your intake arm going to the throttle body and you should be able to locate the screw right above it.

don't want to bash you or anything but this is not the volume on your sterio, you don't just turn it up or down untill you like the way it sounds.

adjusting idle at the cable is a big no no. it should be loose when you aren't pushing the gas and then get tight just as you put pressure on the pedal.

next, your adjustment is what's called an idle screw. if you look at your throttle body from the passenger side of the car there will be a circular opening on the upper side closer to the firewall. it may be covered in grey RTV sealer if the last person to adjust it was properly trained to work on hondas. otherwise you'll see a flathead screw. (oh and it should go without saying but you just scrap out the sealer if it's there and, if you feel like it, replace it with more when you are done.)

there is a procedure to get the idle right on a computer controlled honda (and most other brands of cars). personally, if the motor has a fair amount of mileage on it i remove and clean the IACV. but for your first attempt leave it alone.

step one start the engine and let it get hot untill the cooling fans come on. two, with everything off, (A/C, headlights, other electrical accesories), hook up a timing light with a tach read out. you should be able to rent one at autozone if i remember right. third, pull the two pin connector on the IACV loose and check the idle on the timing light. off the top of my head i think its 450 rpm plus or minus 50 rpm. then reconnect the IACV. if it cuts off, start it up and turn the screw counter-clockwise and check again with the IACV unplugged. move the screw in 1/4 turn increments all while checking the timing light untill it's right. then when you have it right, the idle with it plugged back in should be around 750 +or- 50. you may have a CEL after all this, just disconnect neg bat. cable for ten sec to clear or remove the 7.5amp backup fuse if you have one in the engine bay fuse box.

though it will be good to get this right before moving on, i don't think it is your root problem. do this thought and get back with the results.
