Got a little warm weather and the wife is noticing this year with the AC on she can feel less power a lot more. The car is at about 98K so know it is time for a tune up. Searched but could not find find much tune up info. Know to get plugs and wires. Did a belt and flush not that long ago. Also a PCV. Trying to figure out if there is anything else that I should knock out while doing the work.

Also reading the #2 plug is fun getting too. But you can from the top. What i am not sure about is if I need to remove the rear O2 or not to get to the one plug. Reading mixed on that Only DIY videos I have found are for the Series 2 not 3. The 2's reading that you do not have to.

Thanks for any info or tips. Just do not have these 3800's down yet.
 


That would be the number 6 plug you are refering too.

I can always get them out with the correct extension, crack it loose and then spin it out by hand with the socket.

Clean the throttle body and MAF sensor with the correct cleaners, you will be suprised how black the TB is if you have never cleaned it.

And don't run anything but delco iridums as far as stock plugs go. Never run platinums.
