FERDMAN....all new wires, plugs, cap, rotor, and coil within last three months. Could any of these new parts be suspect? I just put the new wires in last week....Bosch OEM replacement. Out of all the ignition components, which would be most suspect? How to check? Thanks!

For other responses to new Mercedes...you're giving me goosebumps! I wonder how much a can of Redline will actually do for this old girl? I've tried the techron and other snake oils but don't really notice anything...

Thanks for the replies again!

What spark plugs and gap are you using ?

Using NKGs and whatever the specs called for on the gap....can't remember off the top of my head. However, after richening the Lambda yesterday, the car started fine every time today, drove no problem, and idled almost perfectly with no hesitation on take off. However, I'm sure I have the Air/Mixture screwed up now to where it won't pass smog but it ran good today.
