I don't know your mileage (which helps to know), but assuming it's like most cars here, there might be a number of other basic items not maintained--plugs, filters, belts, pulleys--but rather than guess, if you haven't done so yet, get your codes read and search for them here...add them to this thread. They'll help point you in some direction...hopefully the right one. Autozone reads them for free.
-Plugs approx 26k. Bosch +4 Platinums (OEM)
-Belt (serpentine) approx 2yrs (serviced at 170k when trans hose burst on fwy)
-Air (K&N), Fuel, Trans, Cabin filters less than 1 yr/20k, Oil filter less than 5k.
-Trans fluid (Mechanic claimed Esso, didn't verify) less than 3yr/45k, Oil and Coolant less than 5k.
-Never touched a pulley

I'll stop by Kragen on the way home after work tomorrow, thx for the input.
