LINCOLN AVIATOR SPARK PROBLEM

2005 Lincoln Aviator • 115 miles

Code p0171, I feel like I'm chasing a ghost. I was changing the spark plugs and I tested the ohm resistance on each of 8 coils. One was 5234 and the New ones on summit racing advertising6200. Would a reading of 5234 be a problem?

No, check your vacuum lines. A 171 is a lean code
