Ok - So my 99 Sc300 is throwing the P1349 code... It's kind of strange because the day it happened the car did the rough idle at low speeds thing but then went away for a couple of days. It came back as I was on my way to work this morning . I popped the hood and noticed my battery terminal was really corroded. Could this be affecting why my car would be throwing this code or with a code like that would it be completely seperate? Sorry in advance I'm a complete novice!

The car has about 169k on it and runs great. It is due for a tune up but just trying to get an idea of what I am looking at before I take it in the shop!

Thanks in advance!

 

I got the same code today on my gs300
