1990 Ford Bronco 130K miles, 302

Have problems with stalling, mechanic changed the TPS and Fuel Injection computer module residing in firewall. Also, have a hesitation when stepping on the gas, idle or in gear. I changed the plugs, wires, rot, cap, fuel filter. Will idle fine, but will stall if put it in gear or attempt to start moving. Bronco will also stall, while idling, when turning the wheel left or right. Engine light comes on that points to fuel injection problem, but can you help further, is there anything you can suggest that might help us diagnose? Thanks.

What is the code? aslo was the fuel pump pressure tested? Pressure regulator? Pull the vacuum hose off the regulator, it's on the fuel rail, if there is any gas in it replace it. Sounds like its not getting enough gas.

Thanks for the reply, the fuel pump/pressure is ok. The DTC is 63, TPS input is too low, reading at .1. The TPS was changed within the past year, and we’re replacing again today. Do you know why a TPS fails; can it be caused by bad gas? Thanks, Go SOX !!
