My SVT is idleing high yet again. It the revs will drop slowly to 2K then sit there for a while and maybe drop to 1.5K if it feels like it. Sometimes it idles correctly though. I already put a new IAC, TPS, and UIM/LIM gaskets on it. I checked around for air leaks, but I could not seem to find any. If anyone has some ideas that would be great.
