Well, I searched it up on here and found many topics dealing with idle problems when the car warms up. But, in my case its the opposite. My car has a surging idle when i first start it up for about 5 minutes. After its warmed up the surging idle pretty much goes away? What could this be?
Also my temperature gauge fluctuates from just about overheating to normal within seconds. I pop the hood and the motor does not seem like it is overheating? Although sometimes it is glowing red by the cat? What could be causing the cat to get so hot? Could the cat being so hot make the temp gauge go up? I am begining to think that the cat is clogged(?), and it is in turn messing with the air flow or something? Somebody told me the cat or downpiple glowing red could be do to a fuel problem? I dont know im just guessing i need some help...
Thanks to all who reply
by the way car is a d16z6 motor with an CAI if that matters.

the cat is suppose to glow cherry hot, its doing its job...google its function.

as for the slight overheating and surging idle issue, check the coolant level and check for leaks.

 

if the cat is clogged it could get too hot...

 

if it got too hot, it'd melt his catalyst, thus throwing a code if obd2, and only way it'd melt would be excessive fuel, and if clogged ,his car would run roughly.

 

also the cat produces 100 degrees more heat

 

no leaks and the coolant level is fine

 

tighten the cap in the FITV for the cold idle problem see if that helps.


replace your thermostat for the overheating problem and see if that helps

replace the cat and see if that helps with the glowing red.

get back to us after

 

alright im gonna tighten the cap on the FITV to try and fix the idle problems when the car is cold. Its so embarassing especially with an exhaust so its so loud and everyone can hear it.
And where do I get a thermostat at? a dealer?

go with honda oem. they arent expensive at all.

 

this sounds very ghetto, but its a test. take off you intake. there will be this little hole in the throttle body. put a peice of paper over it and see if it surges, then let me know

 

wouldnt use paper, if you loose it and it goes inside the intake...whoopsies.

just cover it with your finger

 

get a bottle brush and intake cleaner and clean out your throttle body

 

do that thing where you plug it with your finger. like said above.
