My wife has an 05 scion tc with 10,000 miles on it. Sometimes after it sits for a couple days or after it rains it starts-up kinda rough. It doesn't do it all the time.
Anybody else having this problem with the tc 2.4? Thanks for any info...

I traded my 05 tc in with 45,000 miles on it and had no problems. Try
