Just wanted to introduce myself. Have a 2001 STS. It's a love/hate relationship. If it worked right all the time I would love it, but there's been troubles.

First off was the starter. Took over 6 trips to dealer to get fixed, but in the end it was fixed for free.

Around the same time I noticed that when the car was cold(this was winter) it would chug like it was gonna stall when I would feather the pedal(think backing out of your driveway. just taping the gas to get going). RPMs jump up and down and car jerks. Haven't quite figured that one out, but hasn't happened as much with the warm weather.

Now I have some air pump(told it had something to do with cat. conv.) making a whining noise for ~40sec at start up. Dealer did whatever, but it's back. Waiting on replacement to arrive.

Have leaky trunk. Found this out the hard way. Tire blew out on the coldest day of the year at 3 in the morning. Popped trunk to get at spare only to find it frozen solid into about 4 inches of ice. Was ready to crash car through dealership showroom after that one.
Finally got around to checking it out today(thanks to the forum). Found that it is leaking right at the trunk latch. Somehow the water is getting behind the seal. Wasn't glued in very well, so for now I reglued. May have replaced eventually.

Last week I had to replace a ballast for the xenon light. Not too bad. Had to drill some new holes in the bracket. Also had a burnt up connector from jumper harness to main headlamp harness, but wasn't buying whole new harness for $2XX. Made my own and works great.

Lastly, I have that damn shimmy around 70MPH. Gonna get some new tires soon and will have road force balanced. See what that does for it.

Anyhow, I mostly just wanted to say thanks. The STS is a great car, and now that I know where to come for quality info I think I will enjoy it a whole lot more. Especially if I can get more performance out of that N* at some point.

Welcome. Your chug may be caused by a dirty egr valve. I had a simmilar problem that was worse when it was cold. Best of luck with your ride:thumbsup:

Check for a vacuum leak and don't overlook the rubber coupler between the TB and the manifold. Speaking of TB's, have you cleaned it lately?

Cleaned the EGR a week or two ago. Did TB at same time. Will check that coupler tomorrow when I'm out there inspecting whether or not my leak is taken care of ::crossesfingers::
