I've noticed that my car sometimes shakes a little bit upon a cold start, but when the temp warms up, it stops....is this normal. I do have an intake and axel back exhaust....maybe that makes it happen???

 

i haven't experienced that

 

I have the same problem on my 03 TL-s

 

Its nothing major...it just a little sparatic shake until it warms up a little.

 

I also got that, its a little knock, nothing major, I assume??

 

Yeah...its almost like a light knock.

 

I was worried, went to the dealer for service, said that my car had a knock, and they couldnt find anything, but it is only when it is cold, then it disapears

 

What year is your car?

 

I have the same problem on cold mornings

 

Since mine is garaged and in So. Cal. my definition of cold wont be the same as yours. My garage only gets down to about 53 even when its 35 outside. I've never experienced this on my 01 with 57k miles though. It doesnt sound right though. I'd have it checked, especially if it is a new issue.

 

Since winter is setting in .. my 03CLS6 shakes like a hay-bailer .. dealer says "no problem" ...

 

Yea, i get the same shake in the morning. I just started noticing it since the weather has gotten colder. Hopefully, it's nothin major!

 

Someone mentioned to me that its because the cars have crappy engine mounts.
In either case, I took my car to the dealer and they said they checked the engine comp and found no abnormalities, in other words they told me not to worry about it.

 

Its got down to the 40's here recently and i haven't felt it shake on a cold start.

 

I wonder if its because of the Comptech Exhaust and CAI?

 

Yeah nicky I have the same thing on my car. I was a little worried but about 2 weeks ago I read a thread about this, in which Jens from parkave replied and said its an issue with the motor mount, its known , but they don't know how to get it to stop .. but in other words he was saying its normal, don't worry about it.

 

its a bit rough for about 100 feet but once it warmed up its ok

 

There was a thread where a guy actually broke a motor mount!

 

after i got my car back from the dealer it seemed to start and run a little bit better

 

maybe its the motor mounts

 

i have the same problem. i live in SoCal and garage my car overnight.

When I first start the car up, it shivers a little bit. But after it warms up a little or if i drive it down the street, the shivers go away. I don't hear any 'knocking', but the car just shivers every 2 secs when its a cold start.

This has never happened b4 until recently. What does the motor mount do? Do you think it has anything to do w/the timing belt? I have about 53k miles on the CLS. I hope this is not a major problem.

Any other ideas?

 

mine does especially with a cAI

 

dalllsion, what did the dealer do to your car? does it not shiver anymore? just curious.

 

The motor mount isolates vibrations. In our cars they are more than just simple rubber mounts. They have either hydraulic fluid or vacuum pressure to reduce vibration. If one of them malfunctions, or take a few minutes to fully "engage", then this is what they must be attributing this to.

 

my car runs solid...shakes a little when its been sitting in the cold but fine after a minute or two. I don't think it's an issue but unless you guys can pinpoint that it is faulty mounts, then I won't be visiting the dealer just yet. Think the CAI contributes to the shaking cuz of the cold air its sucking up on startup...i dunno, it's more pronounced since I installed mine.

 

i think what you're talking about is pretty normal.

 

i know they cleaned the throttle body the 1st time with no difference. the 2nd time they replaced the pcm, which jens said that its an update to the trans, i believe


besides that i dunno

 

If the motor mounts are urathane or hydrolic....maybe they need to warm up to run smooth.

 

i don't hear the "banging " sound i have heard before anymore

 

Dealer told me to let it warm up a bit longer. Seems like a bit of a cop out of an answer, but it always goes away. I figure no worries.

 

mine shakes too. it's been cold up in here and my aem hiss is much louder than warm day.. i'm thinking about removing my CAI for winter.

 

Same thing here, mentioned last time I was at dealer. They told me they could not find a problem. Mine only does it for about the first min of warmup from cold start.

 

same thing happens with the manual tranny models .. I think it is something in the engine management and idle controller .. but acura will never do anything about it

 

no, thats when it sounds the best and gives you better gains

 

I never noticed it before. Nicky, did it just start now for you? Is this something that develops over time?

 

Your motor mounts are going..........Welcome to the aggressive driver club!

 

I don't think my motor mounts are "gone"!

 

i live in canada... i have experienced -20 F... when it's cold, cars do all sorts of sounds and rattle until they warm up... it's quite normal.

Once had a steel shifter knob... on one cold morning, I burned my hand from cold, shifting from one to second.

 

my CLS-6 feels like an earth quake .. i expect NOTHING from Acura .. other than a deaf ear of course
