Took my s10 out for a longer trip this weekend and noticed a few things

1) Take off Chatter - from standing stop, heavy vibration at low speed, accellaration (I had a similar issue with my 99 s10 blazer but that was differential chatter at 10-15 mph due to my 7" lift) this truck is stock. (happens with or without pulling the boat, but much worse pulling the boat) in 2WD mode (didn't try in 4WD)

2) Standing rough idle - truck has 105k miles, just did a 100k tune up, plugs, wires, oil, timing, fuel/air filters - before tune-up it shook the entire vehicle non-stop. now just a periodic shake

Any recomendations for the above issues?
