Civic

[BlasterBob]

My daughter has a 2000 Honda Civic with only 80,000 miles. This car is in very good condition and runs great and quite snappy for a little 4 cylinder. Only problem is that when coming to a stop, it shudders and feels/ sounds like it is about to die because of low RPM?s. She called an automotive shop to attempt to get a ?ball park? figure on what setting up the idle would cost her. Mechanic told her that since it is fuel injected, there is no idle adjustment. Is that true? Of course, guy said it needs a tune up to correct the low rpm?s. Does this sound right. TIA for any reasonable/non-funny/serious responses or suggestions.

Check the trans fluid would be the first thing. Not the idle is not adjustable.

I'd check air filter and plugs first. This forum suggest cleaning IAC (idle air control). Usually the IAC solenoid moves a bullet shaped plug in the throttle body controlling the idle. It gets dirty with blowby gases from emission hoses. Spray and brush it clean with carb cleaner. Link below...

The idle is not adjustable by hand, but there is a idle control valve.
Google search for "2000 civic idle" and look at all the sugestions coming back. Seems to be a somewhat common problem, at least according to google hits. Looks to be a $100 part, may require the car to relearn idle.
Have her go to Autozone or equivalent and see if they can pull any obd2 codes.
Thats the best I can offer with the info you got.

Does it idle fine when in gear? When you put it in gear does it kill or almost kill the engine?

[ChickNorris]

This might be wholly random but have you considered adding staybil to see if it solves the problem?


Worked for me.

Sounds like a loose vacuum hose to me.

Mass airflow sensor?

Had a Honda with similar problem. Turned out to be a bad pcv valve. Basically what Irving said. Vacuum leak.

Go from least expensive to expensive
As people mentioned above and more....

First I would check and/or clean
1 MAF and throttle valvue cleaned. ~$5-7
2. Plug (if you suspect) $15ish
3. Vacuum hose (forgot the price for Hondas)
4. Transmission fluid. 3 HONDA bottle and do mini flush and put another 3 qt after 3mo. (recommended from older hondas)*
5. other stuff mentioned above or thread


* My sister purchased a 2000 accord w/ 70k for $600 from her boss around 2015. Her boss thought it was a bad transmission. Many times, it is wrong ATF fluid and drives weird. After 2 flushes (3qt at at time with proper OEM Honda fluid), it was perfect running shape.
