87 Octane fuel.... is it going to cause problems?? (Idle, etc.)??

I have noticed stutters at idle with my 89 190e 2.6. Is this likely caused from low octane fuel?

I am going to check my overvoltage relay fuse and put in higher octane fuel for a month and see if I get better idles and better cold starting. My wife recently had the car "jump" started.... so I am pretty sure from what I have read in the forum... that the fuse on the overvoltage is the reason for the hard "cold" starts.

Opinions??
