89 escort hesitation

I have a 1989 Ford Escort, 1.9L, CFI, manual tran.
at times it hesitates and will respond to only light accelerator pedal pressure. I did bring the car to a mechanic but it would not act up. they did tell me they pulled a throttle position indicator code and recommended changing the TFI. I have no idea of the role of the TPI and if it could occassionly decide to go on the fritz and if it would cause this lack of throttle response.....the car will rev in nuetral!
Thanks in advance for any advise and ideas.

TFI=Thick film integrated ignition module. Mounted on the distributor. Notorious problem area and a piss poor design by the Ford Motor Company.

Ford is eating repairs/bills for the module replacement. Call Ford with your vin # and see if it's affected. If so, keep your bill from the mechanic and submit it to Ford and you might get some money back.

However, the problem is where the module is placed and it might fail again .
