Getting a little concerned, have 24k miles on my 2018 EX, and when I'm stopped at a light, it feels a lot rougher idling than usual.

Is this normal? Any ideas of what it could be? The RPM's are holding at around 1200, so nothing to do with the engine revving, but it just seems a little strange. I'm going to try to make an appt in the next week or so to get it checked out.

Wait. We don't idle at 1,200 rpm. If you car is warmed up and it's idling at 1,200 rpm then you definitely have an issue.

Am I reading this wrong?

I agree that 1200 RPM is too high for an idling. Before you make the trip out to the dealer try disconnecting the battery for 10 minutes and then drive it a bit and see if the problem goes away.
It may be a setting in the computer that got corrupted.

My bad, it is idling at about 800 RPM

I got into a accident with 900 km on mine. After the body shop gave it back to me I'm experiencing what you are. But I couldn't really remember what it was like before the crash.

Like you said it's around 800 rpm and it shakes the car at a light. But it depends on weather and stuff cause sometimes it's not so bad.

Is it normal?

Same here. Once warmed up, I've noticed more of a rough idle more than the norm.

Check your fuel trims. I had left my vehicle idling for 10-20 min and my fuel trims were over -10% and idle was weird. Some of it had to due to a low battery as well.

Even running, if the battery is low the electronics freak the hell out including what appears to be injector control.

I'm seeing a hot idle of 710-725 rpm on the ScanGauge. Idle should be smooth as silk presuming all is good.

Sometimes I wish it idled/sounded like this:

Never been around a four cylinder engine in a car that was "smooth as silk" while idling, particularly if the idle is a little low.

The firing order of a 4 cyl engine is not conducive to smooth as silk idling.

Ok......guess we agree to disagree. Our CRV idles so silky smooth, you have to look at the tach to confirm it’s running.:nod: Maybe yours needs some shop time/diagnosis.

I'd have them check the motor mounts.

Mine idles silky smooth also. It could also be gas related when you get extra vibrations. I know my older vehicles all idled a bit noisier on cheap gas. I can understand people putting in lower priced gas to save money, especially if you drive a lot of miles. I drive very few miles per week so I put in the most expensive gas.

20 months and 10K miles of Murphy USA 87 octane from Walmart in ours.....has idled smooth as silk since day one. Ours must have a different firing order.

I have an appt next week for an open recall, and will have the dealer check it out. I try my hardest to only use Costco gas, not only is it cheaper, but they also say it is one of the best fuels around.

 

[crv383]

Kinda like those AT&T tv commercials........no body is going to say (their gas) "it's ok.....just ok?". I doubt Costco does their own fuel/oil refining.unno: Gasoline is heavily regulated by the Fed in the USA. That being said, I buy gas based on price and what the vehicle owner's manual says regarding minimum octane.:thumb:

........and it idles smooth as silk.:nod:

agree, if there is no Costco gas stations around I only add enough to get home where there is 2 nearby, and only use regular.
