are you talking about the screen on the rack?

Change your oil, rotate your tires, and check your brakes. Its a solid car. Sometimes they'll have an a/f sensor fail like many Toyotas.

1. There are two drain plugs on the transaxle, one on the pan and one on the differential. Both need a hex socket, remove both with the dipstick out to drain. You can refill with Dexron III or Toyota Type-T4, you might get it at the dealer and ask them for the metal gaskets for the drain plugs. 2. Idle air control motor. Clean it or replace it, be sure to use a new gasket on this also.

i would replace the mass air flow sensor first, sometimes you can clean them, personally i just replace them so i wouldnt know the success rate on that. The knock sensor harness goes out more often than sensors but it happens. I'd bet that its pinging because of the MAF reading and you wont have that 0325 when youre done. What does it do when you floor it from a standstill?

The owner with both sensor codes, this is most likely the knock sensor harness but I would strongly recommend replacing both sensors as well as the harness, this repair is pretty involved and you wouldnt want to do it twice. Same to chococat but you might be fine with the one sensor closest to the radiator.

1135 is Bank 1 Sensor 1 A/F Heater circuit malfunction, its pretty common, just replace the B1S1 (manifold closest to firewall) and clear the codes.
