HI, i have a 1989 Firebird 305 v8 5.0L and was wondering how exactly I go about changing the spark plugs on it?
How do I replace the spark plugs on a 1989 Firebird?
Should be pretty simple. Find the correct size socket to fit the plugs. Pull off one spark plug boot and remove the plug (righty tighty lefty loosy). Take the new spark plug and set it to the correct gap. Put the spark plug in and tighten it to proper torque. If you don't have a torque wrench just get it snug(you do not need to crank the heck out of it). Put boot back one.
Repeat for all of the 7 other plugs. Remember only remove one boot at a time because if you mix up were the wires go then the firing order will be off and it won't run right.
