Tune Up The Es300...

Can a shadtree mechanic toss new spark plugs in a ES 300 what tools are needed ?

Also car shudders hard going down steep hills when i press on the brakes...thinking its the rotors but not sure ?

any help appreciated...thanks.

Make sure you have a swivel socket and a set of extensions for the sockets. The 3 in front are as easy as the ones in back are hard. You have to disconnect some hoses to make the rear ones accessible.
