Help with my SC400 Please!
Ok I'm back to asking questions again. Well as far as everybody knows who helped me out on my last question about the Maf and the IACV I changed both parts on my Sc400 and its still Idleing pretty bad. I was wondering if the O2 sensors would have something to do with that. Because My cel is on and it says that the 2 o2 sensors are bad.
If anyone can help me out with other answers.
Thank You.

you got to get more specific then that. Is it the fronts or the backs? Cuz it could be an exhaust leak, bad cat, or just a bad O2 sensor.
First get that cel fixed and see if it solves your idle problem. If not, then try seafoaming it.

Intake leaks after the MAF sensor cause idling, spuddering, rough running and shut off right after start conditions.
I suspect intake leak(s). Could be at any flange from the cylinder head/intake all the way to the backside of the maf sensor.
That could be what is setting off 02 sensor codes as well. From a super rich or lean condition.
