Intermittent surge?

[jsbihn]

Thanks for the responses.

Here is the answers to the questions....

I have fogged the engine with seafoam about 6 months ago.... maybe a bit longer and cleaned the throttle body, but didnt clean the MAF.
Though, it has been doing this even before that.
The steady sluggish and then normal thing and off doesnt have a speed. sometimes I feel it sometimes I dont. It is really faint actually when I do feel it, but since I am behind the wheel and my "personal sensors" can detect more I feel it.
Given if I press on the gas and it revs up, usually I dont feel it (like if I am pass someone on the interstate)

One person on another forum did happen to mention that it could be my Cats clogging up.... which I do have to say that I have the BAD rocks in a can noise that are coming from the cats I believe .


Thanks for any help you can give
