I have a 89 Crown Victorian witha 5.0
I have problems accelerating. I takes off fine but on the highway if I accerlerate it hesitates and feels like it is not getting fuel. I replaced the fuel pump, filter, and plugs. When I replaced the fuel pump the fuel pressure went from 24 to 35. Please help.

First check all the vacuum lines and fittings for leaks.
Might try cleaning the throttle body, EGR valve and it's port. Also check the initial timing setting and the TPS (throttle position sensor).

Good luck and let us know. :)
