[W126 Coupe] hesitation on 560

[Thomas Oelsner]

Hi Gary
Where and what is the EZL? 

And to all others who would like to chime in...I finally took the car in for a range of service items. New plugs, wires (rotor and cap just needed cleaning as they are fairly new), and the idle is still rough and almost stalled out when stepping on the gas (even when warm). Fuel pumps are good as well as the filter, compression looks good and everything looks good on their test equipment. He did say the cold start valve does not appear to be working when cold. But would this explain the stalling when warm? I am not sure if he checked all vacuum lines for clogs, breaks etc. He suggested the dealer look at it but if I can find a good shop in the bay area that has all the test equipment and codes AND knows these cars, that would be my preference.  The car is originally a TX car so not all local shops have the codes.

Happy Holidays to all.

  Check the vacuum line going to the EZL to make sure it has vacuum and is not broken or pulled off the engine side.
