First off, it's a 95 Civici w/ a 1st gen. B16A. Nothing done to it that I KNOW-OF internally.

I live in SoCal so it doesn't get as cold as it would in other states. But for the last few weeks, the weather has flucuated between cold/warm/hot. In the morning when it's beyond cold, I notice that it idles horribly after I start it. 98% of the time, it cranks, starts, and then does somewhat of a limp idle as if it's running on 3 cylinders, almost dying from idling so low. Sometimes, the car DOES die because it idles so low.

I do notice that once I give it gas for a few seconds, it WILL idle regularly when the car is cold but a CEL light comes on. At this time, the car is totally drivable. However, no VTEC. If I shut off the car and restart it when the motor is warmed up, EVERYTHING is fine.

What I don't get is why it idles like that when the car is cold. I don't want to go through this process every morning and I need to know what's going on. Can anyone figure this out?

Any help at all is greatly appreciated.

-Thanks in advance.

 

mine does that when i start it up ill give it a little gas and it would idle fine but if i didnt then it did what yours is but i dont throw a cel

 

ttt

 

there are alot of reason your car ccould be doign that. bad alternator bad IACV dirty clogged filter check those or do a serach of honda tech

 

I would say.....IACV

or, check your seals...maybe, they contract when they get cold, and expand back when it warms up.

 

what is your impression of butt crack cold, being in SoCal, im thinking that it cant be below 45 degrees, here it has been really cold lately, like it got down to 16degrees here last night.

 

thanks guys i think its my iacv
