P1639 in a 00
Hi, in my 2000 v10 4R100 setup I get a P1639 code, the only one.
It will not start when temps are 30-40F 'ish I can smell the gas in the exhaust so fuel is being delivered by injectors. When warmer it will start and runs pretty smooth.
It has a Diablo eeprom upgrade from many years ago, I am not sure how to swap it back to stock. I do not have the original eeprom if there is one that needs to go in it.
Some advice would be appreciated.
