Default Slight Sputter

Its a 00 WS6 with 126k on the clock....It seems theres a slight sputter or maybe a misfire when giving it any gas. I just had the plugs replaced with NGK TR55s but the coil packs and wires are stock, although they looked ok.
There arent any check engine lights. There doesnt really seem to be much loss in power, just not running as smooth as it should be.
Whats weird is when Ill flip the a/c on or off while driving, the sputter will stop for a just a split second and then start again

Any ideas?

Driving the car tonight I kinda noticed it almost seems like a vibration, more so than a sputter. But its hard to describe so im not sure

Do a search... But basically seafoam is a petroleum product you can put in the gas tank and also the oil to clean some gunk out of the engine...


Anyways, Any ideas on what this sputter/vibration could be?

Have you tried seafoaming yet? After 126k it could use it (if you haven't done it yet before) and I wouldn't be surprised if that fixed it.

Well.. I bought a can of seafoam today and poured it in the gas tank, I will do the other steps when im close to changing my oil again...
I didnt have a very long funnel tho, the spout of the funnel wasnt long enough to push open the little metal plate, I didnt sea the sea foam lekain out anywhere under the car tho...

Well considering that my plugs right now are original from 98 and are burned off so bad that I can stick a quarter in the gap yet there is no SES light I doubt it

Yes, I'm being serious. That is how bad my plugs are, apparently the previous owner just never bothered to change them (along with a few other things..) I have new plugs to go in but I haven't gotten to it yet, will do it after I seafoam the car.

O2's would set off the SES light for sure. Plugs/wires could if they weren't firing but as long as they spark then it won't set it off.
