I am dedicating my weekend to bringing my 97 Deville back to perfect running shape. I want to change the oil, oil filter, plugs, plug wires air filter. As far as the oil, oil filter and air filter, I know what to get. For the plugs and wires, this is the first time I have ever changed them on my own. What should I buy ? Should I check and re-gap the plugs before I put them in ? Any help would be greatly appriciated.
Before I go ahead I have another question. I bought my car with roughly 85-89k miles on it. I switched the plugs at the time, but not the wires. Should I change them again with 195k on the clock ? How would I know the wires are still operating to par ? Thanks

Re: Complete engine overhaul, need help ASAP
Always check the plug gaps before installing them. Usually I would say, "if it ain't broke, don't fix it", but at 10 years old with almost 200K it is probably due for wires. Stick with A/C Delco. They obviously has proven to be reliable.
