97 sc400 high idle when cold issues??
Ok so I have no vac leaks and my idle valve is working properly as well as intake is very clean so maybe I am over looking something here but when it warms up it seems to be fine but in the morning if I put it in gear it is almost like a "neutral drop" so I have searched alldata as well and no avl
No cel's or bending dtc'c either

ISCV can still act up even if it looks clean and gives proper resistance -- mines doing it right now even though it seemed okay. Are you 100% sure its working as specified?

Before the second cleaning it was about 1200 in gear which of course is way to high now it seems to be 600-700ish in gear which is a 100% improvement from before but what stumps me is the fact that I cleaned it a month ago and there was no improvement but this time I took it all the away apart and that seemed to do the trick.

Hi everyone,
I hope someone can help me with an issue I have with my 92 SC400. I've had a misfire for a couple weeks now which I was told can be solved by doing a tune up. My car would normally start at 11-1200 RPM from a cold-start, but today I started it from cold and it was at 500 RPM and there is no change from 500 RPM. The car now will not maintain normal speed even when I floor it. There is no CEL on. Is this a cold start issue? I'll get the tune up to begin with and hopefully this cures the misfire and the unusual RPM I have. If anyone has any info about this issue I would really appreciate it.
