I swapped an v6 engine out of a 1993 626 at. Installed it with all the stuff off old motor like distributor, intake manifold, exhaust manifold etc.
Started it and it ran good but now as soon as you try pushing on gas pedal it starts to crap out. New plugs, wires, cap, tps sensor. Fuel preasure is with in specs, coil tested good too. Seems to be running so rich. Will idle smooth. Don't know what else to try. Maybe PCM?

Were all sensors on the engine switched? Has the check engine light come on?
