When the temp drops below 40deg F, it won't start. Been chasing this for year and about out of ideas.There no codes. Once it is started it runs great and after the first start of the day, it will start all day long. If you hold the throttle wide open, sometimes it will sputter and start and appears to be rich and will run normally once running. Took it to the dealer for computer trouble shooting nothing but $45.00 for the hookup no problems they could find. I have checked or replaced the following: All vacuum hoses Ck'd the electrical connections Replaced both 02, MAP, Intake air sensors and cleaned the butterfly and injectors. Throttle position and idle speed motor cks out electrically.
Any thoughts or suggestions would be appreciated.
