I've read that the Denso Iridiums can resolve my idle vibration, any truth to this?

 

What type of idle vibration are you having, and did it start with the addition of one of your mods ?

 

Nope!!!!!!!!!!!

 

Is this a common occurence on CL/TL ? I Must not have noticed if mine has it or not .

 

here's the link to my original thread on this topic -- Acura claims it's my headers:

Common on Type-S's due to the larger cams. Not ur headers either. Did u ever think it might be ur crak pulley???If not that then it could be a hundred things...but not ur headers and iridium plugs won't help!!

 

I have a bone stock 03 CLS w/ 3k on the clock and have experienced the vibration you mentioned since day 1. Like Ant7701 said, it is partly due to the relatively hot cams. I think the high compression ratio, transverse mount design and shitty motor mounts also contribute to this.

i put the densos in and didnt notice a damn thing. The only thing i can say i somewhat "noticed" was the quicker accelerator response. Not worth the money unless your are spraying or going FI and need colder plugs. You might notice it on the dyno with all the bolt ons, but the butt dyno feels nothing.

 

so i shouldn't waste my time or money putting the stock headers back on to see if it'll get rid of this vibration?

 

I notice it too. More so with the cold weather though, I think .. but I had my headers installed this winter so I dont know if it'll do it in the warm weather.

 

I had it since the day I got my car. It goes away once I drive for alittle bit.

 

My car shakes and squeals when it is cold, once it warms up I can barely hear a thing. Dealer said they couldn't re-create the problem. Since I live an hour from the dealer I can't get it there cold and have it make the noise. I think one of the pully's is off balance, any idea what may have caused this?

 

the crank pulley actually made it better after I had that installed. I had the headers installed for a whole 7 months before I began to notice the vibration. Comptech said that occassionally, the flex joint on the headers can malfunction (this is that mesh pipe fitting) .. the purpose of this flex joint is to reduce vibration from the engine that is transmitted to the car and the rest of the exhaust system. That's why i'm curious to re install the stock headers to see if it'll go away.

 

I can deal with a vibration or two to have the power of the CT headers .. I'll NEVER GO BACK TO STOCK

 

can you check to see if the motor mounts are bad before going to the dealer?
