Odd Idle Surge...

Hey Everyone, just had an interesting question, my 97 GT surges at idle, when it's cold or warm, all the time, just leaving it run, it'll sit at 700rpm for a few seconds, then jump to 1200, then back to 700, then back to 1200.... and it does this constantly.

(It did it stock before I put exhaust on the car, so that can't be the problem! it's just way noticable now that the car's considerably louder than stock)

does anyone have any idea the cause of this!? could it be like a semi-plugged fuel filter or something?

TIA

** sorry about the thread title, I was typing too fast as usual! **

You could try cleaning your MAF. Here's an article on how to do it. http://www.svtsnake.com/tech/mafclean.html The article is for 03/04 Cobras but the same method is used with our cars as well.
