Civic EG

ok, so i've been having some really weird issues with my idle. i start the car it runs ok when it's cold but then after it warms up the idle drops really low, as in 500 or less. and i have alot of bogging anything below 2,000 rpm. and i will randomly throw a CEL every once in a while. i just reaplaced my oil pan and my vtec solenoid gasket.

this is a b16a in a 92si. as i said i'm at a total loss.

Thanks
Ian

What CEL is it throwing?

i have no idea, how do i tell?

oh and i noticed today on the freeway that when im at a constant rpm, when i go to give it gas i have to almost mash it to get anything out of it. help me out this is really annoying.

check the IAT sensor and turn the idle screw down more.

Check your Idle air control valve and the fast idle control valve I have had the same problem on both my Sol and my civic once I change the fast idle valve worked sweet as a nut.

i figured it out. i got the code it's throwing an O2 sensor code. so i'll get that replaced then i'll go from there

Might not have to replace it try giving your current one a wire brushing, DON'T use anything else then put it back in and see if that does the trick could save you a few pennies.

good idea, thanks

if the sensor is burned up it may be a waste of time. but if your gonna go that route at least get yourself a good O2 sensor removal tool. When I swapped the exhaust on my S2000 and had to pull the secondary o2 sensor off it made the job a million times easier. all it is is a socket with a cut in the side so the cable can go thru it. Rachet>combo wrench any day of the week

change your iACV sounds like its bad.
