can you take out the spark plugs out with the engine still in the car.....its a 97 legacy 2.5.......is there a special tool?

There's a tool in the original toolkit, even has a rubber ring to hold the plug in firm.

Go s-l-o-w, lay all the parts out in order as you remove them, and keep all the bolts, nuts, etc in order (I like to put them back on loosely after I remove the part). Then after you have replaced the plugs and wires (do both), you just work your way backward down the line of parts until there are none left on the floor!

One thing: the plugs are mounted way down in pipes that penetrate the valve covers. Think before you go to actually unscrew the plugs. All you need is a ratchet handle (3/8" drive probably), socket wrench, and 6" extension. HOWEVER...use a proper plug socket -- it'll have a rubber insert that protects the ceramic, and more importantly, will grip the plug so you can pull it out. MOST IMPORTANT: unless you have a locking socket...duct tape the socket to the extension. Otherwise, when you go to pull the plug, the socket will come off the extension, and you'll be left wondering how to get the socket and plug out of the pipe.
So, not the easiest compared to many cars, but it's all pretty easy and can be accomplished by even a novice wrench.

hey its done and done the plugs were on.....the insulation on the inside of the plugs around the lower terminal was brown and chalky.......the car was overheating due to a head gasket failure so they may be the same plugs from then ......would this effect my mpg?
if the plug gaps are wrong yes.

by how much? 1-2?
thats hard to say, if they are really off may be higher. sometimes that dont affect them at all.
