i posted a post on here a few days ago about a CEL i got code # p0131. front o2 sensor.
the same time that light came on, my car would idle really low at stoplights and would actually stall a few times. the weather was hot and humid that day.

i pulled the fuse from the fuse box under the hood and the light went off and the idle seemed fine for the last couple days and the weather was cooler.

today, the light is still off which is good, but the weather is hot and the car started idleing low again and stalled.

even since the CEL hasnt come back on, could the o2 sensor still be bad and could a bad o2 sensor cause a low idle at stops?

2000 ex with 87,400 miles.

thanks

Is the low idle related to running the A/C? If so, when you turn the A/C off, does the engine then idle normally?

 

i am not running my a/c at the time.

 

What engine do you have?

 

2000 ex coupe, i believe a d16y5 or something like that.

 

Do you have a CVT transmission?

 

If you are not sure, these diagrams may help:

 

no CVT

 

I am looking for a diagram that tells you how to set the idle on your Civic, but I don't find a diagram for a 2000 D16Y5 with a MT. Is the engine possibly a D16Y7 or D16Y8?

 

ok i looked, it is a d16y8 motor.

i dont think it is my idle. it runs fine on cool days, only started once the CEL came on few days ago during hot weather.
