I suspect the VAFS (Vane Air Flow Sensor) on my 87 Camry is sticking? I am experiencing engine hesitation upon initial acceleration. I removed the top of the air filter box and moved the flap with my fingers. It moved freely. I removed the 2 screws that secure the wiring plug to the air clearner lid but found several attached connections within the air cleaner lid that I could not disconnect. Your advice is appreciated.
