Just noticed that my car idles funny in park. It's like a slight intermitent shudder. Not huge but you can feel it. What could this be. I was thinking either one of two things. Either the oxygen sensor is going and the fuel mixture is off or the intake manifold is all gunked up and needs to be cleaned which is likely seeing that I have 82k miles right now. I was hoping that I wouldn't have to do this 'till 100k miles but I'm not sure. I've been using Prestone gas treatment for the past couple of months and my gas mileage has shot up from 320 per tank to 390 ( 'till the gas light comes on ) so I'm not so sure that it's the intake manifold. Any suggestions would be appreciated, the idle is bugging the sh@t out of me. Thanks

P.S. sorry if this is in the wrong section. Please feel free to move it if it is.

my car does the same so any help would be appreciated!

hey prtyatmoontower I have the same issue. Could be either of those two things you mentioned, doubtfully the O2 sensor though, but possibly. No worries it's not going to be a big problem. You could be proactive and remove IM and clean it with carb cleaner which would be great to do anyway. BTW do you know any good import shops in NH or ME.

try changing your spark plugs.. search up on iridium plugs..

prtyatmoontower

I just did that about 2k miles ago and I changed them to NGK Iridiums so I know it's not that. Sorry sbuswell I try to do as much of the work myself as I can and anything that I can't I have the mechanic that works next door to my shop do but he doesn't specialize in anything.

mine does it as well, and also when im driving with the rpm's around 2k

I have this problem too. It's like the car is cold or something and it shivers.

the problem could engine/trans mount related depending driver. had an acura feild rep in the shop a few months ago went though absolutly everything even adjusted valves and still done the same. the car also had 3 trannys per customer for this problem and no change - so take a close look at your mounts to see if they are leaking.

Yeah well mine does this too and my friends Honda does also. It is the car cycling. It is not a big deal. Mine is worse when the ac is on.

I have a weird noise with the air con compressor or something. Feels rough when idling... Any suggestions for that?

Well I had the same problem a while ago, and it was just built up shit in the intake manifold, and a clogged EGR port, and clogged EGR valve. It runs like its brand new now! I also changed my spark plugs too. I had my ignition switch replaced today under warranty (recall) and there is nothing wrong with my car anymore!!! WOOHOO!!! Well, knock on fake acura wood.... I'm driving the thing to Orlando on Friday.

Cleaning IM will be a big help. I need to do that too. Great suggestion. While cleaning IM, cleaning EGR ports is easy from what I've read here.

Comet2404

Well yea, I guess it is if your technically inclined. I didn't want to risk it, and I'm a chicken shit, so I payed my mechanic to do it.
