The plugs are to last for 100K but different driving conditions can cause them to wear sooner. In my book, the 100K is under perfect conditions.
As far as the cleaner, any parts store will have it. Just tell them you want to clean the MAF. It is a cheap thing to try and doesn't take long.
Truly, at nearly 90K, plugs, wires. Could be causing problems. You may want to consider replacing them. I can't guarantee it will fix the problem, but it can't hurt. Consider it preventative maintenance. Same with the fuel filter if you never replaced it.
Let me know how things go, and Happy Thanksgiving to you too.
