My car did the exact same thing. Wouldnt smoke on start up but after it would idle for a few minutes after it warmed up it would smoke. Changed the Valve stem seals when I did my timing belt and havnt had a puff of smoke since and that was about 10,000 miles ago

Not much to mess up. 4 bolts if your changing the rotors and pads. Now drum brakes on the other hand I can understand not wanting to do as thier are alot of springs and adjusters to deal with. Disk brakes only thing to mess up is not tightening the bolts all the way or cleaning the film off new...

Have you checked advance auto parts?

When you let off the throttle its going to go lean that in normal. I'd try a new coolant temp sensor.

I'd unplug the VSS and see if it show something different on the gauge. If you have a scan tool that scan shows live data, logger or DSMLink then you can also look at those and see what the computer is reading as far as vehicle speed goes.
