First of all, if the check engine light comes on, then why are you reseting the light without pulling the code? Or have you pulled the code? If so, then what is the code?
Also, there are many more potential problems other than the ECM. Besides reading what the computer is trying to tell you, you need to check your ground cables from bat to engine/frame. As well as the wiring of your sensors/ECM/Transmission for burned insulation, corroded connectors or even something unplugged.
Other things that will cause your problem: Vacuum leak, clogged air/fuel filter, bad coils/plugs/wires, leaking fuel pressure regulator, bad fuel pump.
