1) Sorry, but what is CL?I'm trying to find out from another member of our forum two things (this time)
1) With the fuel system in CL car in drive at idle what exactly is the engines RPM
2) What is the normal cooling temp when idle the engine in +90 F weather
That is what I thought you might have meant with CL but just checking. Thanks.Thanks all for the info. Sound about the same for mine. My other two cars idle after warm-up at 650 to 700 the MB is only 500 to 550 it seemed a little low that's why I asked. As for CL it stands for Close Loop. It means the engine has warmed and the exhaust has reached a temp that the O2 sensors can start to read and send info to the ECU befor that it's called open loop.
