If you cannot find 91, you could try filling at half a tank instead of letting it run lower, and alternating between 87 & 93; the resulting mix should be OK. Kio,

I changed the gas to octane level 87 yesterday after reading this post. The lowest level I could get around here. Thanks to you guys, this morning, it started on first try! I bought my MCS a month ago and now I remember this cold start problem started after I refill the gas with 92 octane level gas. I see some people on this post saying 91 will work, too. So, next time when my MCS needs a gas, I will fill up with 91 and see. My question is … is it okay keep using lower octane level of gas for a long time? Does anyone know?

Maybe that explains the preference for 91..!! ;) I don't have the cold start issue (at the moment) but I do have the 'lumpy' idle. Maybe I'll look for 91 and see if it fixes that too.

Go figure. My rough idle doesn't seem to have any rhyme or reason.

It has been humid, and my car doesn't seem to like the humidity much. Unfortunately, it's only been *not* warm and humid for like a couple of days since I've had the car. :-P Yeah, RB, Indy.

I called MoP and they told me to run 91. So, I have the UNIchip and switched it to race mode... running good now. If anyone has a UNIchip and this issue run race mode. It's like running on a cold fall day. :) I have also noticed the rough at idle. I called MoP and they told me to run 91. So, I have the UNIchip and switched it to race mode… running good now.

I haven't noticed it leaving work, but then it hasn't been exactly cool during the days here (Boston area). The gas stations I usually stop at have 89 or 93, not 91, but it may be worth a diversion. On my previous car (94 Ford Taurus SHO), many people had to use the trick of moving the key to on but not start and wait a bit. Or even move the key back to off and on again before starting. That usually meant your fuel filter was clogged or your fuel pump was failing (or both). I’ve only had my MCS about three weeks, but also notice the rough running when starting in the morning.
