My SVT has started revving on its own- Just had an new IAC valve put in 5 weeks ago, and now coasting to a stop light, the revs will slowly climb to 2500 or 3000 rpms... its not throwing any codes yet, and I haven't cleaned out the EGR passages in the TB yet (but might get to it this weekend)
Has anyone had this happen before? TPS? Its got me baffled.. It was doing the same thing and the dealer had some work to do on it and replaced the IAC and it fixed it for a couple weeks, but now its back and worse..
