I had a slight stumble and had v36 installed. Worst thing I could have done. Now on warm mornings (above 55 deg.) my S sputters and stalls when I first start it. I just had v37 installed and it stalled this morning. Thoughts?

 

When you start in the morning, turn the key to the position 2, but don't start it right away, wait a couple seconds. After a second or two, then start it and it is less likely to stall.

 

No problems here with V36. Temperatures here have been in the low to mid 80's with high humidity (60% to 100%) percent.

Thanks, I have tried that too...no luck

 

Our 03 MCS does the same thing. Did it last spring also, then seemed to correct itself. It started doing it again about a week or so ago. Haven't taken it in yet, but plan on it. We've not gotten any software upgrades either, still whatever was on it when we took delivery in November of 02.

 

I had v.37 installed in December. Never quite got rid of the stumble, but that's another story. Anyway, about 1 week ago, it starts up with the ignition crap again! I have to start it twice every morning now... Suppose, like you, that it's the warmer weather. Oh goodie. Another fun summer is on the way.
