Anybody have the GM troubleshooting guide for a code P 0171?
Checked the search function here but didn't find the solution. I did check what was mentioned (vacuum leaks, fuel pressure, etc.). There was even one member that fixed it with an SAIS valve. So I'm stuck and hoping to get the page from the manual with the diagnostic procedure on it.
