I have been searching and reading forum posts for hours today trying to decide what to do next. I've read the EDS controls idle, and bumps it up at cold start. Warmed up it looks like RPM's is 600 and is smooth and quiet. At cold start up it trys to idle but bounces and shakes around, and will die. I would say RPM's bounce between 600 and 750. I have to keep my foot on the throtle a little to keep it running till warm. What should I do next? Get the codes read? Just replace the coolant sensor by thermostat? Maybe it is telling the computer a false signal? Would just resetting codes work? I've read a post on making a box to count flashes/read codes but, can I reset codes by shorting out a couple pins on that plug up by the battery? I am on vacation and trying to get this car going to drive next week. The car is SO much better than when I bought it, but I still need to get this this issue figured out. Thanks for any help.
