Engine problem
1997 Ford Ranger 4 cyl Two Wheel Drive Manual 195, 00 miles

Hi
What is the best way to find a vacuum leak on the engine. I have a P0171 fault code (system too lean). A freind said that can either be caused by a vacuum leak or a bad mass air flow sensor. I'd like to check for the vaumm leak first.

Do you
have the same problem?
Yes
No

Get a can of gumout and spray it around your vacuum hose's and intake manifold. When you hear your RPM change, you have found your leak.
Happy New Year :)
