Check for Vacuum Leaks First!
Vacuum leaks present symptoms similar to a faulty MAF Sensor. When replacing the MAF, always check for vacuum leaks, too. Common sources include:
Leaking Intake Manifold Gasket (found in the "Engine" category) - Vacuum Gauge readings below 17-22 in-Hg (normal manifold vacuum at sea level) at idle may indicate an intake manifold gasket leak.
Note: As elevation increases, readings decrease. Subtract 1 in-Hg from normal manifold vacuum reference for every 1,000 feet increase in elevation above 2,000 feet.
Stuck open PCV Valve - remove the PCV Valve and gently shake it; if it does not rattle, the valve is clogged or dirty and should be replaced.
Cracked Intake Boot (found in the "Engine" category)
CAPA Certified or NSF Certified parts bear the seal of independent, third party organizations guaranteeing fitment and quality equal to original equipment. These parts may be required if your insurance company is paying for the repair.
