p0505, I think is a problem with your IAC valve.

Ok, yeah thats what I was reading. However, would the iac cause the flashing trac light?

I'm still new to lexus / my Is300 but from what i have seen yes the trac light will flash on and off if the check engine is on (not just for iac valve) i think they did that to get your attention lol but also dont expect ur trac to work when that check engine light is on cause it doesnt lol ( Alittle slideways ) lol
