Well, my service engine light came on this afternoon .. there is only 220 miles on my new Mustang .....

Any guesses as to what it is. It kinda soudnsl iek their is a high whistle when i accelerate, but I htink its jsut when the engine has been in the cold for awhile. It goes away after 5 minutes of driving

Geeze ...

 

there's been a few threads on it. It's because of a problem with the gas tank vent tube, if I remember correctly. try a search, you should find it. as far as the whistle.... I can't say.... perhaps you got one of the 7 dwarves under your hood.

 

Ya...here's two of the threads I found:

you're such a nice guy... I was too lazy to search myself

 

My ECU picked up a misfire that didnt happen and Ford is working on an update right now.

 

I have the whistle too. Kinda sounds like there is a blower under the hood!

 

ya exactly!

Well, i did just get gas ... a different grade. We put the highest in the first day we got it cause the fill up was free ... but I put in 2nd grade yesterday. Hmmm

 

The Gt is programmed to run on regular, you only throwing money away running anything else.

 

Well, the first fil.l up was on the dealer, so we put the highest grade in cause ti wasnt our money.

 

wanna bet??????
