My short term and long term trims are up a bit and I suspect a vacuum leak so im trying to troubleshoot.
While researching fuel trims I came across an industry professional that made this statement:
On engines that use a manifold absolute pressure (MAP) sensor to determine airflow, a vacuum leak does not affect fuel trim because the extra air (pressure) in the manifold is still measured by the MAP sensor.
Sounds plausible....true or false?
