Bring it in for a tune up,

Make sure they put on.. good wires and plugs.. many places will use cheap junk.

AC Delco plugs
AC Delco, Napa Belden or Autolite Professional wires
Fuel Filter
Air filter (thanks Mark)
PCV Valve
Remove and clean throttle body.

That should get a good jump on the issues.

Plugs, wires, and air filter are DIY jobs! Don't pay someone else labor charges for a maybe one hour driveway job!!!

Ok I will admit I am mechanically challenged.Where is the idiot guide to removing and cleaning the throttle body? Or should I just go buy a chiltons?Now I am assuming that by doing all of the above should pretty much take care of the need for a tune up?

Techinfo has tons of stuff and should be able to help you.

The gap for our plugs is .060 and listed or should be on your radiator support cover.
