I had a similar issue on an older car I used to have. It turned out the intake hose had a crack in it. It looks normal at idle but would widen when I applied the accelerator as the car "took a bigger breath".

Like mentioned, I had a stumbling issue for quite a while and it was very annoying. Mainly after car sat for 7+ hrs. The problem lasted for only a minute, then al was ok until the next time it was cold. I ran a diagnostic and nothing, after about a month or so I finally got the CE light and then I had a code to look at. It was a misfire in #6 cyl. Changed plugs and she was like a brand new 21 year old chick! If your plugs have more than 30K I would probably start there if you don't have any good leads.

Another thing to do is clean your MAF sensor. I haven't cleaned mine, but I do know this little thing can cause your car to feel like it's vibrating and shuttering.

OK - cleaned the MAF, replaced BMC filter with stock, and even took out my sprintbooster - And still nothing has improved =/

I'm just really trying anything.

Just so we're clear as to what's happening:
So, this stuttering, only happens between 30-40 mph while cruising or very lightly accelerating between this MPH range only. It doesn't happen at any other time.

I think I'm just going to wait for the check engine light to go on now. Lame.

Thanks to everyone for their inputs though - I really appreciate it!

Problem solved!!!

So, here's what you have to do - it's a frikkin tranny reset!!

Drive in manual mode M5 for 5 minutes at over 60MPH, then switch it to M6 for 1 minute, then back to M5 for 2 minutes, then back to auto.
Note: the car is going to sputter continuously when you have it on M5 for the 5 minutes.

That was it - drove around for 30 minutes afterwards and no issues what so ever!! Unbelievable!!!

Is there a cheat sheet tricks thread on this forum - we really need one if not - this was an amazing trick!!

Anyway, I'll report back in a week to see if this is a possible long term fix.
Then, I'll just need to find that post again so I can buy that guy a beer or 10 if he's local!!

Forums FTW!!!!!

Just tried this trick. Let's see if it works after I drive around again tomorrow.

Nice tip!

How did you stumble across this method anyhow?

p3style

Good luck!! If you were experiencing the exact same problem it should work.

Let me know how things turn out!

I'm still amazed - if I took it to the stealership they prob would have told me I needed a new tranny!

It was a google search - but, I still can't find the forum link who I got this from.

But, I followed his instructions to a T.

And he even said that the car will sputter like crazy in M5 mode for the 5 minutes - which it did - so don't freak out to when it happens.
