Hello,

My 190e rarely starts on the first try (hot or cold). It turns over fine, it just doesn't quite "grab" when it is supposed to fire about 90% of the time.

The second try is 100% effective in starting. Under the same conditions (hot or cold) it always fires right away on the 2nd try, though it does hesitate and stutter for about 1 second before the engine comes to full idle. After that it is as smooth as silk...

I just had a full tune-up with the last 4k, and I use 93 octane all the time. I'm about to run a tank of gas with techron added to see if that helps any. I would appreciate some ideas of what to check and look for to smooth out the starting...

Thanks,

Todd
