Re: How to replace Spark Plugs on a 97 2.3L
This is an aggravating task. I changed the plugs in a truck I bought with well over 100,000 miles - fun, fun, fun. If you want detailed steps (found these later) search for "97 ranger how change spark plugs posted by Steven in NC" - very good. Before staring, wash down the engine, especially around the plugs. Then spray the plug seats liberally with a good penetrant, such as Liquid Wrench - doing this several times over several days may be needed for high milers.
In addition to Steve's suggestions, I found a stiff 18" length of wire helpful to hold the plug wire up, while pushing into place. Also, using masking tape on the socket swivel to keep if from being too flexible -especially on #3 & #4 driver's side helped.
