I got a question for all you gearheads. My 01 Type S (56K miles) shudders when iddling in PARK, but not when stopped at a redlight or at a stop sign in DRIVE. The shuddering isn't that bad, but I'm picky about my car. I guess it could be a number of things but any ideas off the top of ya'lls heads would be really appreciated. My thoughts are that it may have something do with 1. Transmission recall service done not too long ago OR 2. my car needs a fuel injection cleaning. New belts maybe?

 

Do the interior lights dim?

Could need an intake air control valve adjustment/cleaning/replacement.

 

mr steve do u have a part # on that???

 

mine does that too i think...its not a steady shuttering just kinda every 10 seconds or so it will shudder for like 1.5-2 seconds...no one notices it but me so im just like

 

It is a pretty constant and soft shuddering, and no the lights don't dim. When I first start the car it doesn't ussually do it, but if I've been driving around for a few minutes and then put it in park in traffic or something then the shuddering begins. No one really notices it but me either but its quite annoying on a vehicle thats suppose to be a near luxury car.

 

Is it dependent on whether your air condtioner is on or not?

 

nope, shudders when AC is on or off. I know some cars shudder when its cold out but mine does so if its cold or hot outside.

 

Does it shudder in neutral, also?? i.e. no load on the engine.

 

Mine does the same thing, except it will do it in park, and it will also do it right before i come to a complete stop (its not a warped brake rotor shudder, its like an engine dipping to low in the revs type shudder). I have no clue what it is.

 

my car shudders a bit when im braking when i got off offramps at like 70 or above, could it be the rotors?

 

your rotors are warped its a lost cause unless you upgrade from OEM to rotoras im on my third set of OEM's and i just said the hell with it

 

Bad engine mounts? Put it in neutral and see if it will still shudder.

 

Yeah, I put it in neutral today and it was shuddering.

 

Sounds like your motor mounts are bad. I'm on my 3rd set!

 

Then it's probably not the transmission; could be engine mounts, blown head gasket, air sensor, etc.

Best have a dealer do a code check and general diagnostic.

 

now im getting shudders every 5 seconds or so right after i start up, at least they go away after i drive for a few minutes and they dont happen all the time

 

how many miles do you have? Mine used to do that also, then when I put on the OE thermoblock spacers, I cleaned out my intake manafold and EGR port with some carb cleaner - now it idles and runs good as new. I would try that because I have 85k miles and my EGR port was 100% clogged up with carbon buildup and the intake manafold was dirty also.

 

Do you use premium gasoline?

 

it does not do when you first start the car because the car is running a cold start cycle...

do you have any Accesories running (A/C, heat, radio=system)

You mentioned something with your tranny... did you get the tranny replaced?.. if they replaced your tranny, they more than likely replaced your ECU as well.

where are your RPM's sitting at idle.. (20 minutes) after you start the car?

 

you need to go to the dealership and find out the problem and report back.

 

im sure its not a big enough deal to run to the sealership...I bet the EGR port is getting clogged up and just needs a cleaning.

 

what's the warranty for our motor mounts.

i think mine might be going bad.

 

what's the warranty for our motor mounts?

i think mine might be going bad.

 

it might be classified as a wear and tear item...

but my guess would be as long as you have factory warranty you should be able to get any problems rectified.

 

anyone know offhand what dealers are charging to replace motor mounts if no longer under warranty? How hard are they to replace?

 

My dealer replaced the motor mounts under the warrenty.

 

My car's shuddering too, park and in neutral. Interior lights are dimming, and idle drops below 750. I do know the CL needs a desperate oil-change...

Lights dimming doesn't sound too good, as these cars have a hell of a charging system IMO.

 

yea i always use 91, i jus got my oil changed and all the fluids refilled and its gone away, but it appears randomly sumtimes, i only have close to 55k

 

this may be a bit off topic... but i notice that my car shutters sometimes when upshifting to like 3rd gear; is this the tranny problem?

 

i jus checked wit my friend and he said my shuddering is from my torque converter trying to keep itself running, btw it only shudders when im in reverse and havent moved newhere yet
