I suspect the VAFS (Vane Air Flow Sensor) on my 92 4x4 3.0 xtra cab is sticking? I am experiencing engine hesitation upon initial acceleration(like lifting my foot on/off the accelerator). 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. Any advice is appreciated.

 

I think you undo the wire clip to remove the connector.

 

I don't believe it's your VAF, but here's some info that might help:

Good Luck!
