Drives like shit... I mean, it's still driveable and someone who never drove a CL-S would probably not be able to tell anything but I can feel it. It began suddenly too. It was perfect then just started to move poorly... I changed the air filter, checked the plugs (they are fine), there are no check engine codes.... where do I look now?????? Are there any common occurances like this with these cars?? I haven't had it for long...

thanks in advance

 

Is this under WOT? Or just normal driving?

 

IMRC possibly. Search the forums for detailed explanations on the Intake Manifold Runner Control actuator, it's a somewhat common problem and cuts deep into the car's available power. You can test it yourself.

 

I checked the actuator.. it opens at about 4000 rpms..... i pulled the plugs and they look good.. but the powerloss is on the low end.. and all thru out the powerband, but a lot more felt on the low end........

 

This happened to me, it was a bad coil pack. But it was throwing codes left and right.

 

Coil Pack was gonna be my suggestion.

 

Could be the ECU. Check out this thread: https://acurazine.com/forums/showthread.php?t=179237

 

yeah i have no codes, it just runs terrible. I have extended warranty with a 250 bucks deductable, I know, retarded. But basically I don't want to take it in, pay $250 and they won't find the problem or the problem is something a lot cheaper.
