91' f-superduty 7.5l 125k mi

truck idle is erratic
when you realy get on the gas when in park is boggs out
when in drive if you get on the gas at all it will bogg out


replaced the throttle pos sensor
replaced the fuel filters

any ideas?

its my work truck and im in need of it. it would be great to solve the problem at home rather then take it to a shop.

thanks so much

Fuel pressure would be one thing to check, along with computer codes. www.fordfuelinjection.com shows how to do it.
