Has anyone in this chapter done the subject fix? If yes, may I please take a look at it? I live in Arlington, Va., FYI.

My "Cat" is a '99, ATX, 6-cyl., stock. Not sure if this is related to the TH fix, but lately, her RPMs surge/fluctuate, even when there is no load on the engine.

Thanks in advance,

I did the TH fix a couple years ago. I have noticed when running some of the accesories my rpm's can wander, but nothing major. I had it in when i dynotested with no ill effects.
