Subject: [Land-speed] Off Toopic: 1991 F150 Truck Issues
I spent 17 hours this week end with another guy and we made some very
good progress on the truck. Itseemed that everything we touched had to
be redone in some form or fashion. After being tolf that the exhaust
manifolds, the cast iron ones, were the same as what came off the truck
to begin with, when trying to fit up the down pipes, fout out otherwise.
Finally located a y pipe that fir the motor with odd manifolds, but no
O2 bung. Some connectors not connected. Late yesterday found a
connector a the far back end of the manifold not connected. Suspect it
is for a knock sensor but this block has no knock sensor threaded hole
location. The engine runs great above 2000 rpm. Runs like crap at 1000
rpm. I have run out of ideas and gumption in working on this thing. If
there are any other ideas about why it would not run at 1000 but runs
like a scalded dog at 2000 lemme know and I will pass it along..
See ya'll on the salt...
