My ranger starts fine then starts to miss after it warms up. approx. 10 min. Changed distributor,control module,cap,rotor,wires,plugs,coil.Checked fuel pressure which was 35 psi. book says thats normal. Newer fuel pump as well as fuel filter. Also have a donor truck with parts so I went and changed out the TPS ,IAC valve after I cleaned it and the manifold pressure sensor. Still has the miss after it warms up. So I decided to run it down the road and the truck has intermittent surges and struggles to reach speeds of 55 mph or above. I have no clue to what might be wrong. Also there is no check engine light on.Any help greatly appreciated. Thanks in advance.
