1987 ford mustang 5.0HO engine pops and shakes when cold, runs ok when operating temp is reached. I have installed new fuel tank & pump, serviced the injectors, new cap, rotor, plugs & wires, new timing chain & gears ( lined up the dots on gears. It is an aod trany, tps is at.98 at idle 700rpm at operating temp. Timing is at 12 degrees BTDC. Smog pump is eliminated and egr valve vacum line is of. I dont know what could be wrong.
have the same problem?
