is250 - tune-up

Hi,

I have a 10' is250 with 105k miles. Besides oil change and air filter, I have not done anything else to the car. It seems to run well minus a PO303 code which didn't come back after a reset.

What are the recommendations for plugs? I'm thinking that I should also clean the throttle body and MAF. Any other suggestions?

Thanks in advance
