I havemarried intoa 94 mx6 with a 2.0 automaticthat had been sitting for 5 years. The car is in good shape but it has some runability problems. It started with the fuel pump not working. I replaced the pump.plugs,wires,cap,rotor,air and fuel filter. When i drive the car it seems like it is starving for fuel. It has good psi to the injectors. The ECM is not giving any codes. Today it would not get over twenty until the coolant temp was in the normal running temp. Then it seems as though someone flipped a switch and it was back to the regular problem at hand. Any ideas would be greatly appreciated.

 

Try cleaning the MAF.
