I still have a code 43, rough idle when the engine is cold. When the engine is warm it does one of these two things
1. surges to about 1700RPM then drops to about 1100RPM, repeat... etc
2. Idles high at about 1700RPM until a CEL comes on and drops dow to about 11-1200RPM and holds steady.
The car has also started dieseling when I shut off the engine.
Here are links to videos that show the idle when cold and the idle surging
:::EDIT::: Since this post I have taken apart, cleaned, and reinstalled the FITV and the surging has gotten just a little better... other syptoms still exist, crappy quality idle, etc.
have the same problem?
