Nobody Cleans This Sensor And that's Why Your Car Shakes When Idling

In this video we explain how eight critical engine sensors can quietly fail due to dirt, contamination, and electrical resistance, leading to power loss, higher fuel consumption, rough idle, random stalling, and failed emissions tests. We describe why the MAF, MAP, O2, TPS, crankshaft, coolant temperature, and intake air temperature sensors lose accuracy, and we reveal the single overlooked fix that can solve more problems than replacing parts.
