How do you change the plugs and wires in a 97 Pontiac Bonneville?

Answer 1

Well.. For starters we need to know the engine in the car is it a 3.8 L? (It will say 3800 on the engine) If so then one at a time remove the wires form the electronic ignition pack (Black rectangle with six cables coming off it) for the rear bank of plugs and wires you'll have to remove the engine cover which is the part that says 3800 to do this you must remove the engine oil filler cap and neck (hold by neck and turn counter clockwise till it stops then jsut pull out) and lifting on the engine cover note that it slips underneath a clip and the back of the engine to hold it down and make sure you get it under the clip when you put it back on.. Remove the plugs and wirse one at a time and replace them as you go. What I mean is do the first one, pull the plug and wire, replace the plug and replace the wire witha similar size one from the kit. A warning to you, Sparkplugs are fragile.. and if you break one off in the engine you're in real trouble I would suggest that if you aren't entirely comfortable doing it; get a mechanic to, regular tune-ups are not really expensive but if you break off a plug you're looking at big money because you engine has to be taken out and practically rebuilt.
