- NEW!
by tech1962 on January 3rd, 2009
Same trouble, here! My 1993 F-150 4.9L 5 speed also idles fine, dies upon acceleration, and I have replaced everything, except the distributor and F3TF-TA computer!
Changed out with new, Fuel Filter, Ignition coil (no change to symptoms!), wires (3 were broken), cap (had corroded pins), rotor (normal, discolored metal), plugs (3 were gapped wrong), TPS ( was intermittant), tested the MAP, replaced a blown electrolytic capacitor on the T3FT-TA computer (10uf@63VDC), O2 sensor looks new on this just purchased truck.
Catalytic converter is gone, replaced with a FreeFlow muffler.
When I get a solution, it will be posted!
