Idle Problem (d16y7)
I searched the other threads and I didn't find anything quite the same. Heres my issue. I have a 97' Civic Dx Hatch. Its starting to really get up in the weather here (80's & 90's) and in the morning while its still cool my car runs fine however as the day heats up it starts to start idling real low. Like I pulled up to a traffic light and it went real low sat there for about 5sec and stalled however it starts right back up. when im driving its perfectly fine, just when i stop has a real low rough / stalling idle. Engine wise its all stock except for a no-name short ram intake w/ a k&n filter. Was fine till hot weather hit...Any help is appreciated. What i got out of the other forums is that it can be my thermostat, water pump,map sensor, or my IACV... Im new to the world of tuning so im not to knowledgeable yet. I bought new coolant and injector cleaner today however as i got home it started poring so until it stops that is all delayed...
Thanks, Mike

Re: Idle Problem (USDMxEk4)
If your CEL is not lit, I would suggest replacing the PCV valve, or cleaning of the IACV with brake cleaner.
The crankcase supplies 40% of the engines idle air from the PCV valve to the engine at idle.
