Thank you for the reply. Believe it or not, I resorted to using the homemade DTC code reader described by Jim F and Arthur Dalton, etc., and that WAS able to reset the codes that the fancy pants Trisco Palm Scanner could not. I will probably check with Trisco to see whether there is a bug in the version of their scanner that I have. The car seems to be running well now, but then again, it has been COLD in central Indiana, so not sure what will happen when the engine gets hot again.
