Just so you know, you have to find a way to ingest the foam cleaners in a way that does not come into contact with the MAF yet still have the vehicle running to ingest properly. This can also, like Sea Foam, as an side result throw a plug or sensor over the edge if it was on its way out anyway, as you are probably aware with any carbon expelling products like the ones in question.
Anyhow, for your car(which?) perhaps look into the atf subforum for issues with those symptoms. I got hesitation before in my Stratus going into OD/TC lockup around those speeds, hesitation then bogged/loss of power. Better when fully hot and absent of cold weather.
Replacing the filter in the pan, adding fresh transmission fluid and 1 1/2 bottles of Lubegard "Red Bottle" has symptoms gone. Sold the car to a family member last year.
I'm aware of the side effects possible. One of the reasons I asked about seafoam was due to the potential pain and suffering on my part if I use it. Interesting suggestion about the A/T. Thing is it's practically new - I had it replaced 7k miles ago with a GM remanufactured unit under warranty. I'll probably know more once I consider any carbon issues resolved. I'll probably pull a few plugs and see what they look like while I'm at it.
What I really would like to do is just reset the ECU. I've heard so many different opinions on doing this that I'm not sure who is right on the proper method, other than a reflash at the dealer.
I found a really old forum thread on this topic about a week ago...can't seem to find it now.
Most cars you can just remove the neg cable on your battery for a few minutes then reinstall. Could go to autozone, etc and have them check for codes and to reset your computer.
