I gave my '92 300CE a tune up this weekend thinking that my hard starting problem may go way. Didn't work.

I guess I should be asking for some help but before I do I should explain about what I mean about "hard starting problem". Living in So California perhaps it actually is not as much as a "problem" as living in some other colder regions. It is just bothersome that when I get into the car I have to crank it twice before it "catches".

I have replace the following:

• Air temp sensor
• Rotor
• Cap
• Plug wires
• Plugs

Just a sore spot with me, I like to have my cars running near perfect as possible. Could there be something else causing this "problem"?
