300E -Solved: irregular idle and sluggish warm starts

The '91 300E was starting to idle roughly again when warm and would often stumble at warm starts.

I thought I should do the Techron cure again. A parts counter person said I'd be better off using a $1.79 bottle of GumOut injector cleaner than Techron. Somewhat surprised I gave it a try.

Wow! Good advice. The idle is smooth and no stumble-starts when warm. Hah, $1.79! I like it.
