I have done that already sprayed for leaks had a line off that went to the map sensor unplugged,connected it and light stayed off for 4 days..i can go to autozone and see about trying another maf

 

Good luck. They might be able to test it for you too.

 

I will do 1 more test with it unplugged..

 

K. Just don't drive around for too long with it unplugged. It will F' up the cat. You really don't need to drive around at all. Just leave it plugged in until it throws the P0171.

 

didn't throw code yet,autozone said they have another one to try...

 

Best of luck!

 

Got the new one and so far no code... Wonder if the cold keeps it rich enough not to throw one and when it warms up will it make a diff.. 19 here now

 

The temperature shouldn't make a difference. Keep me posted.

 

light came on today 171..about after 40 miles

 

Soooo sorry to here that. I still have to wonder if you're missing a vacuum or LIM leak. What type of spray did you use to check for leaks? I encourage anyone else out there to chime in. Are we missing something? I went by the book.
