Re: '87 Ranger w/ 2.9 V6
my experience is that the 2.9 will go like the proverbial bat outa hell
check for bad cat converter, also check fuel pressure, I think the 87 still
used the two-pump system with a low-pressure pump in the tank and a
hi-pressure unit on the frame rail under the driver's seat
also the pressure regulator (rear of fuel rail on driver's side) goes bad,
also check the vacuum line from regulator to manifold for gas
