I have a 93 supra. The car was running perfect 3 days ago. I went to crank it up about an hour after drving it home and the idle was realy rough. Decided not to drive the car. The next day I cranked it up and now it idles steady at 1800 rpms. Drove the car around the block and it is running very rich with a little black smoke. I need some help please! There is no CEL
have the same problem?

Remove and clean the IAC.
Generally a high idle is a vacuum leak. Check all the vacuum lines for cracks.
They get brittle with age and constant heat cycles, abd can crack very easily.
