hey guys just dropped off my 03 cl s to the dealership so they can check up on some problems. it stalled out the other day while in park and when im idle it shutters and shakes. I also feel like my cl has gotten slower and less responsive. i valet and i drove an 01 cls with 20000 more miles than i have and it felt much more responsive and had quicker acceleration than mine with no mods. the dealership called me and said that they cant find any problems. anyone have any idea wat can be causing this? they are keeping it another day to check it out some more. please help. thanks

 

Fuel Filter? Fuel Pump? Needs seafoam or injector cleaner? or both. Plugs possibly? Someone wanna chime in? Maybe the IAC is bad. I'd personally take a look at the fuel system and IAC.


Sorry I'm editing so much but more and more things come to mind...

 

Check ur plugs..

 

^^^^^like he said

 

just start narrowing stuff down...like they said^^

check all the filters cuz theyre cheapest, then maybe plugs, if nothing then...look into other factors

 

try searching on here for "broken actuator". that could be it.
