marciemarc3 Posted March 18, 2014 Report Share Posted March 18, 2014 Hello, I hope that somebody can give me some advice about the following: Mine car (shelby GT 2007 Automatic) has some trouble with cold start up. It cranks but has trouble to start at once. When the motor is hot there is no issue. We replaced battery and spark plugs. And the PCM tells that the fuel pressure is OK. The PCM gives measurement of an AAT ( air ambient temperature) sensor. What is its function? it gives -20C Maybe i am searching the wrong way. So any help is much appreciated. Kind regards, Marc (from the Netherlands) Quote Link to comment Share on other sites More sharing options...
