I Had A Problem With The Acceleration Of My Escort Wagon. After Much Grief I Found Out The Damper Pulley Has A Rubber Insert That, When Worn, Allows The Damper Pulleys To Rotate Slightly.
This Changes The Timing Point On The Pulley And That Tells The Crankshaft Position Sensor That The Engine Is Advanced So The Computer Responses By Retarding The Ignition Timing Resulting In No Or Long Drawn Out Acceleration.
Change That Damper And Your Problems Are Over.
