if there is very little to no water coolent or antifreeze in the radiator , will the car's idle go up and down up and down when warm??? cause i have an integra computer and it isnt throwing any codes on my b16

 

car idles fine till gets warm and then idle goes up and down up and down up and down and wont stop, could this be cause there is not enought antifreeze, or water, or is the O2 sensor broken , this is open header no exhaust and i have no check engine light ?? any one know why its idle liek that

 

Could be a few things. Check your coolant level, IACV, timing, look for vacuum leaks, do a basic tuneup, check your PCV valve.

 

so ur saying coolent would be a reason it would be doing this the idleing?

 

I have the same problem on my B16

Why wouldnt you just check the antifreeze and if its low add some and see if it helps? I doubt that it has anything to do with no antifreeze in there but I guess you never know?? But I would just check it fill it if needs be and then go from there. Its such an easy step why wouldnt you want to check the coolant level??

Yes it will. On Hondas when the coolant is low, the idle surges. I think it is because the coolant temp sensor doesn't read properly, and can't decide if the engine is hot or cold so it keeps kicking the high idle in and going back to normal.
