01 3.4 LS MC Stalling & sputtering while idle
Hey everyone, I've been a long-time lurker on this forum, but only today decided to sign up because I couldn't find an answer to this particular question.
Yesterday while driving, my car stalled 5-6 times. It was always when I was either idling at a light, or turning (i.e. going very slow). I was always able to turn the car right back on, until I was at another stop. The thing is, it isn't producing any codes. From what I've read, it could be a large number of potential things, but they seem to always produce codes. So, I wasn't sure where I should begin. I haven't had a tune-up since about October, though I haven't driven much through the Midwest winter.
I'm really busy this weekend, as some of you may be as well with the holiday, so I will get around to checking out air filter and MAF tomorrow evening if I can.
Thanks for the help and happy almost Easter!

There are lots of things that can cause this. My first thought is checking the maintenance history. If the spark plugs have over 100K miles on them, I would advise replacing them (the plugs used from the factory are good for 100K, 150K max, but after 100K, they could be worn and not giving a good spark, low speed/low RPM and it's just not enough to keep it going).
