will ebpv cause this?

Ok its my dads 96 350, He said it started losing power on the way home with almost no power when he got home. Now it will start with a slight rough idle and free rev fine but as soon as you drop it in gear it dies. checked for codes and it had one for ebpv malfunction and saw that it doesnt move when the truck is started. So the question is will it cause this problem or do I have something else wrong. Thanks in advance.

Nobody has replied so I guess I will. But if it's throwing a code for it then I would check it out. If you hear it closed through the exhaust then it is mostly like your problem.

The EBPV will only actuate if it's rather cold out. Once the engine is up to operating temp it never actuates the valve. So seeing as it started acting up while he was driving I'm guessing something else is going on.

If it was stuck shut you should hear the engine choking up from it. Just make sure the EBPV actuator valve is all the back in the pedastel, then unplug the EBPV actuator. This is the little 2 wire connector on the front of the turbo pedastel. If you unplug this then it won't be able to push the valve shut.

Alot of times you will have a EBP related code, but they can be from a few things, like the EBP sensor tube plugged or the EBP sensor not working. You would almost need a scan tool to moniter EBP pressure while it's running to narrow down a EBP issue.

Since your not getting any codes I'd start with checking fuel pressure, then I'd pull all the injector wiring harnesses going into the valve cover and check for melted terminals.
