hey guys,
my Honda civic isn't idling normal when on neutral whats the problem

 

epic thread

 

WOW your gunna get ALOT of help with a thread like this.
What car? what motor? any check engine lights? this is all stuff that will help us help you.
Your statement is like me saying I farted and it smells....ok?

 

lol

 

check your canooter valve and muffler bearings

 

Especially the name.

Seriously though, we need more details to help you out.

 

yeah moar details.

Year, trim level, and transmission would be a good start. Engine would be a plus if it's not the right one for the car. It would be nice to know what kind of idle problem it is. Hunting? Surging? Up and down?

99% of the time though, idle problems are caused by the following:
1. Vacuum leak somewhere
2. Air pockets in the coolant
3. bad/dirty IACV or FITV
4. bad/dirty throttle body

 

My RPM sits at 1.5k RPM on neutral..seems kinda off too
I just cleaned my IACV yesterday as well

 

hey dude
the engine idling goes op and down. it is a D16d engine civic ek5.
i had an accident with the car. the car was at a body-shop for a month.
when i took it t was idling high above 1000rpm.
whats the problem. the check engine lights is off.

regards

 

You mean it's constantly going up and down, on its own, at a regular interval? 99% sure it's a vacuum leak. There's a hose with a hole in it, or not connected.

Now, if it's sort of randomly idling a little high, then a little low, then a little high, and can't seem to find a place to settle at, that's a different problem.

You should still try bleeding the coolant. Start cold, take the radiator cap off, and make sure radiator and reservoir are full. Then, turn the heater on full blast and run the car at idle with the radiator cap off for about 20 minutes. That should get out any air in the system that might be causing your idle problem.

If neither of those solutions work, then it's time to start looking at idle air control valve or throttle body problems.

 

t is constantly going up and down. but when driving it doesnt do it

 

vacuum leak then. You either have a hose disconnected, or a hole in a hose.

 

i was gonna say something more like epic fail but that works too lol
