My friend has a 1995 F250 with 115k miles on it. It has the big V8 in it (7.3?).
When decelerating, the engine wants to stall at 15 mph. He replaced the throttle position sensor and the vacuum regulator solenoid.
No luck.
He connected a vacuum gauge from the vacuum regulator solenoid to the EGR valve. The engine is pulling 5 to 15 inches of vacuum at 15 mph, i.e., the vacuum solenoid is opening.
Any ideas so he doesn’t have to “chase more parts?”
Thanks.
