Most people recommend changing the ect too.
What octane fuel are you using?

Clean your MAF meter really well.
Also unplug your battery for at least 30 minutes after doing the above tuneup to reset your computer.

Even if it doesn't help with the pinging it's something you should do anyway, especially if you have a K&N which tends to gunk up the MAF wire with filter oil.

It doesn't have to be THAT long, but that would definitely work if you're not going out tonight.
