I don't have an answer for you, but I am having a similar problem with a 1992 Lexus SC 300. It was running great & now it is running rough, won't idle & is blowing black smoke. Did you get your problem resolved? If so, what did you do?

My 1992 Lexus SC 300 with 120,000 miles that has been running fine until recently it started running poorly & dying with a puff of white smoke. Installed a new head gasket, but still running poorly & dying. Took it to a Toyota dealer & they thought it may be bad gas. Had them drain the tank. It ran great for 3 days. Now it's back to running rough, not idling & blowing black smoke. Toyota wants to try replacing the ECM, but they are not sure that is the problem. At $1000.00 I want to be reasonably sure that is the problem & not throwing parts at it until we fix it. Anyone have a similar situation?

Does anybody have fixes to this problem? I have observed this in other SC 300 & 400's.
