2004 Bonneville SLE - P0101 and P0172

truc0011 · 09-18-2008, 10:25 PM

Hi Everybody,

I'm getting a P0101 and P0172 error code. The car starts (Starts very hard) when it is cold but stalls after a few minutes of running and will not restart until it cools down.

Any help is appreciated.
Thanks.

101 usually is caused by a bad MAF, or connection. 172 is a rich condition, a full scan would look at the input from the maf to the pcm for a better diagnosis. Disconnect the maf and see if the condition improves.
