Re: 01 taurs lean codes
After replacing the plugs in my '05 and cleaning the throttle body, i too am getting lean codes for both banks.
It's running fine,and won't get check enging light for 200-300 miles after resetting the computer. Getting 27-28 mpg combined, and purrs like a kitten EXCEPT when I really lean on it, then she pings just a bit? (110K mi)
Did I possibly screw up the MAF (didn't get spray near it), or should i replace 02 sensors (light on all of a sudden after plug change!?!) or should i chase down a vacuum leak?
If vacuum, where is most common leakage point?
