Bucking 90 F150
I have a 1990 F150 with a 300EFI and 5 speed. My problem is that it starts bucking when the outside ambient temperature is hot, not the engine being hot. Also when the bucking begins the cruise control will not work. It does not buck and the cruise works when it is cool outside. I have changed the EGR valve, coil, plugs & wires, pip sensor, TPS and vacuum switch on cruise control, battery, cables, and MAP sensor. Any ideas would be appreciated.
