First off your spark plugs are designed to last 100,000. I changed mine at 100,700. I bought Iridium A/C Delco at Auto Zone cost 6.99 each. They are pretty easy to change. I decided to clean the Throttle body removed it and cleaned it out with Throttle Body Cleaner. I also decided to clean O2 flow-sensor with Flow Sensor cleaner. Then changed out air filter and fuel filter. Oil change and new oil filter. Put it all back together. Then reset PMV by removing fuses for about 15 minutes. I also inspected belt and other fluids. Then started it up and now I get 1-2 more miles of driving per gallon which is much improvement and have much better acceleration. I was driving on fwy and speeding as I did not realize it. If I missed anything let me know. Cost just a little over $100. 00.
